Info Center Introduction

Welcome to the Sid Meiers Civilization IV Information Center!

This information is meant to give anyone a deep, factual understanding of Sid Meier’s Civilization IV (the sequel to Sid Meier’s Civilization III) as well as Civilization IV: Warlords (the first expansion pack of the base game). The article will keep up to the very last detail of information that is currently available to us.

Material is gathered from all sources available (in a detailed manner) and put into this article as one organized piece. This should make it very easy to find virtually everything you want to know, without having to surf through multiple places on the web to find what you need. You don’t have to be a
Civilization III veteran to understand what we are talking about here, since this is a brand new Civilization… a historical simulation/strategy game series which has won multiple game awards, and which is accepted the world over as being the greatest, and finest turn-based strategy game series on the planet!

The game has been released, but it does not mean that this article will not
be updated with more news as it comes (patches, expansions, etc)!
This information is up to date as of Monday, July 3rd, 2006, and up to the latest available bit of information.

As information changes, or is released, I will be updating this as soon as possible so it evolves to be factual. I recommend that you check out the updates (when they are posted), so that you stay informed, and up-to-date as well. Checking the “Miscellaneous Information” section occasionally can also give you a heads-up on some other things either in regards to this article, or other information. From what we have gathered so far, as well as the great reviews the game has been receiving, I believe we can all form our own opinions of it.

This is the most detailed and extensive, most viewed, and also the most updated place for all things Civilization IV from around the web.

Currently, there are a total of 360+ gathered game details, with nine new additions! Don’t miss out, discuss the article!

The Big Picture

Here we’ll look at the very basics of the game, from its creators and the design elements they implement, to what general game-play aspects it will contain.

• Development & Producers: The new Sid Meier’s  Civilization IV was developed by Firaxis Games (based in Hunt Valley, Maryland, U.S.A.).
  It is much more streamlined and full of personality. Unlike the Civilization III series, the publisher will not be Atari, as they have sold off the Civilization Franchise to Take-Two Interactive. Take-Two confirmed this on January 26th, although it has been known that Atari sold the Franchise since November 24th, 2004. The game was published under Take-Twos publishing label 2K Games.The senior producer of the game was Barry Caudill (he produced Sid Meier’s Pirates!), and the producer Jesse Smith.

  Jesse was the producer of Civilization III: Conquests as well (the last, and most commendable expansion of the Civ3 series). The project lead, and lead designer of the game was Soren Johnson, he programmed and co-designed Civ3 along with company CEO, Jeff Briggs. For more information on Firaxis staff, check out the Bios section on their website.

  • About 38 people have been dedicated to certain segments of Civ4 (terrain, cities, interface, etc). It will take thousands of people hours to complete the project. Firaxis also says that they have many (100+) active Civilization fans testing and giving feedback to Firaxis. This number is rising. However fans have been giving feedback since June of 2004 in a private online forum.
  • News that Civilization IV was in the very early stages of development first came on December 4th, 2003.Development of Civ4 most likely started around Spring time in 2003 (more than two years ago). At around the Fall time of the same year, Firaxis had an early Multiplayer version up and playing. The basic game-play elements were established then. After that period (around May of 2005) much more attention has been given to improving the AI (or Artificial Intelligence).
    The game hit Beta in August and from then on, much more attention was given to polishing up the different aspects of it. Civ4 went Gold on October 19th, and shipped on the 25th, although most people got their copy on October 26th.
• Good news for Macintosh Gamers! Civilization IV will be available for the Mac in early 2006 [source]. Aspyr Media is bringing the game to the Mac. Civilization III: Complete (featuring both expansions of Civ3: Play The World and
  Conquests) will also be available for the Mac later this year, in December.
• Firaxis Memo: Firaxis has updated their “Behind the Scenes” section on their website with a new Winter-edition Memo. The part below includes content on Civ4:Civilization IV has been flying off the shelves and has received loads of great reviews. We want to thank our fans for your unwavering support, and particularly for your tremendous feedback that helped get us through some initial technical issue right after the release of the game. Our team worked tirelessly to fix the problems quickly and post a patch to help those folks experiencing difficulties in running the game. Civ fans are truly extraordinary! And dont forget… Santa will be bringing another gem of a gift in January… the Civ IV SDK! This is an unprecedented offering and we cant wait to see what all of you budding Civ designers will create!
  • “Civilization is much more of collaboration between
    our designers and our fans. We’ve had a lot of feedback over the years about what works and what doesn’t in Civilization and it’s had a big impact on the final game.” – Sid Meier said in a GameSpy Interview.
  • Many conventions which have remained the same since Civilization I (which came out in 1991) have been rewritten to ensure a quality new game.
• The game was written entirely from scratch using flexible XML data files, as well as the Python scripting language. Boost.Python (this allows for seamless interoperability between C++ and the Python programming language) was used as the interface layer between the C++ game code and Python. Python is used in the game for map generation, interface screens, game events, tools, tutorials, etc. If you want to see how this will affect customization of the game (or any other aspect relating to customization), look under Customization Flexibility. The new 3D engine will also allow for greater possibilities (find under A New Expression).
• Firaxis main focus is aiming to keep the game true, simple, but mostly to lose aspects which are not fun (find under Controlling Your People… by Decree for aspects which have been removed because they are not fun to the player), and to maintain a successful Civilization Franchise.They also plan to break free of some bad habits from previous Civilization titles. For more information on maintaining a successful Franchise, see the PowerPoint entitled Dont Blow It!, by lead Civilization IV designer, Soren Johnson. An article that relates to the PowerPoint is “Civ4: A Model in Franchise Progression” where Soren talks about the challenges of improving on a successful model while simultaneously keeping hardcore fans satisfied. That being said, Civ4 will not be totally different in concept than Civ3. Don’t let this fool you into thinking that it will just be a small improvement over Civ3, though! Remember, it is rewritten from scratch, so there is a lot of change/alteration and major innovation.
  • In order to fight team fatigue, Firaxis will rotate its design responsibilities (with different lead designers).
  • Firaxis will not be afraid to slightly change its target audience a bit, as keeping the same audience will lead to the loss of a certain percent of people per cycle. They will still, however, make base fans comfortable with the same fonts, icons, and map placement, a similar number of units on the screen, etc
  • Civ4 being a maturation of the franchise (since it will focus on more multiplayer, and modability, unlike Civ3, as it was under a lot of pressure), they will keep adding more game-play/design innovation and not just adding more content or “Stuff.” Making everything a little better will be much less compelling to the player than a significant improvement in just a few areas. Soren also quotes Electronic Art’s (EA’s) Bing Gordon that “1/3 old, 1/3 improved, and 1/3 new” is a good rule of thumb. Simplifying old systems will leave room for new design elements.
  • Firaxis will also “borrow” useful elements mostly from Real-Time Strategy (RTS) games. An example with Civ3 was the distinct civilizations, unique units, abilities, and multi-unit forces or armies.
• Civilization IV will continue on to what Civ3 has had —
  The core game-play concept still remains the same. It is a turn-based, tile-based, historical simulation/strategy empire building game. You are put as the emperor of a powerful civilization, ruling your empire by decree, with one goal in mind: to stand the test of time (which has been the appropriate slogan of Firaxis). You start out with a small tribe and lead them to greatness, to the post-nuclear age and beyond.
  • The game is even more about strategy than ever.
    It is more about decision making and less about the established motions that have built up over the years.

Release Date

Perhaps this is the most important question to most people. When will the game actually be released?

• Take-Two Games has pushed the release of
  Civilization IV up by a few weeks. The game was released on October
  25th, although most people didn’t get the game by the 26th in North America. Click here (from the official Take-Two website) and here to read more on this (from GameSpot).
  • 2K Games had launched the Sid Meier’s Civilization IV Pre-order program. Here is a quote from GamesIndustry.biz:

A New Expression

The look and feel of a game are very important to most players; the description of these can be found here. For screenshots, visit the “In-Game Visuals” section.

• The Graphics Engine Civilization IV is using is the NDL’s Gamebryo 3D graphics engine. Firaxis’ PC hit, Sid Meier’s Pirates! also uses it.
  • The engine will naturally provide an engaging 3D world with unparalleled scope and detail. Soren also mentions in his PowerPoint that the game has a “What-you-see-is-what-you-get,” approach to it, meaning that the terrain does not lie in terms of what it displays. An example of this are Great Wonders. When they are built they will be displayed on the terrain near the city which built it.
  • Rivers and resources such as horses and elephants are animated. You will also see different animations as the resources are being worked on, and of course, many other aspects which make the world more dynamic.
  • Due to the move to 3D, Barry Caudill (senior Civ4 producer) says that the largest maps in the game are slightly smaller compared to those of Civilization III.
  • The new 3D engine will allow for powerful, smooth zooming, from a global level, to a very local one. The tiles of Civ4 are plain squares, rather than the diamond view we had with Civilization III (when viewing the game from the default position). The Camera views are very flexible. You can spin it around any way you like.There is a Civ3-Style Isometric view, and the classic Civilization I top-down view. You may zoom in and out by using the Mouse-Wheel (speaking of Mice, Civ4 will even have its own specific Mouse-Cursor).
  •  You’ll see Aqueducts go from the mountains or hills into your cities when they arebuilt.
• A Random Map Generator, like previous Civilization titles,
  will form unique worlds reflecting the settings you put in. The Map Generator is one of Civilization’s most successful aspects, because one cannot play on the same map twice without wanting it, so replayability is very, very high.
• Continents are the default world setting. “Standard Size” map you will have about five to ten cities. By that time, your borders are established and it is a race of who can advance through the tech tree faster. By that time, your oldest few cities will also be the “core” cities of you empire.Here are the different map sizes: Duel, Tiny, Small, Standard, Large, Huge and
  of course, Random. There are no restrictions on the number of Civilizations you
  are allowed to play with on a certain map size. You can have all 18 Civs on a
  Duel map. The map widths in Civ4 are about double than what they used to
  be in Civ3.
• The Mini-Map starts out zoomed in when the player starts a new
  random game. As they explore, the Mini-Map will expand. This has been done so exploration is a lot more interesting each game.What it means is that when one starts a game, he or she does not know exactly
  where on the map they are. In Civ3 the player always knew where they were exactly in the beginning. Now this is not the case at all.
• There is a Global View, in which you see the whole planet. There, you can also use options to filter thing such as resources, units, trade networks, cultural borders, religions and more. Below are three examples of the powerful new zoom. Details such as cloud cover can also be seen in the Global View (first image):
  
• Music for Civilization IV is also a major focus. Jeff Briggs (Firaxis’ CEO) himself is taking charge of this aspect of the game (and he is perfectly suited to do so as well, since this was his first career). Jeff anticipates that Civ4 will have much more music than any other game ever released. The game will include music from some of Jeff’s original compositions, as well as licensed performances by old greats such as Bach, Mozart, Beethoven, company, as well as contemporary greats like John Adams and Christopher Tin. Here is Civ4‘s opening soundtrack: Baba Yetu.
  • Jeff will also be composing the music for all 28 wonder movies included in the game as well as all of the game’s diplomacy music.Where possible, folk tunes are used to represent the character and attitude of each Civilization and each ruler. The music for Franklin D. Roosevelt for instance is the Marine Hymn. Jeff has also gone as far as to arrange each piece of music to fit the various time periods of the game. If you meet with Roosevelt in the early part of the game, you’ll hear ancient instruments playing the theme. By the end of the game, the tune will have swelled and taken on a more Sousa-like quality.
  • Firaxis is also hiring voice talent for various game parts. Ambient sounds can also be heard, when you are over different terrains. For example, if you are over the ocean or on its shore, you will hear waves splashing and breaking up. When you are over desert closer up, you will naturally hear very dry winds.
  • When clicking on a unit, that unit will respond in the language
    of your selected region or Civilization.
  • With each built improvement you’ll hear a sound related to it
    when it is accomplished.

User Interface & Control

Control is a very important aspect for any game. With Civ4’s new interface, ruling you empire just got a whole lot easier.

• To start a Single-Player game: You must choose your map style (some
  options are: Archipelago, Continents, Custom Continents, Highlands, Great Plains, Inland Sea, Lakes, Oasis, Pangaea, and Terra) and size, climate and sea level and Civilization you want to play. You can also select whether you want aggressive AIs, Random Personalities, etc. Also, AI personalities are stored in XML data files.
  • In the “Custom Game” menu (there is also a “Play Now!” option which allows you to start games quicker) there are a variety of options and combinations. In regards to map scripts there are much more. The “Custom Continents” option allows you to select exactly how many continents you want in the game. The “Highlands” map scripts allows you to select everything from mountain density to lake size. Of course, the most random map options you have are the classic “Archipelago,” the basic “Continents” setting, as well as the regular “Pangaea” option which allows you to also set in different shore options.
  • There also the “Aggressive” AI setting where AIs lean towards war instead of diplomacy.
  • While in the process of loading, the game will display tips for certain things from Hot-Key commands to strategies during war-time. Here is a screenshot which shows some of these. Note that when the game actually starts, you have a very similar Civilization introduction as in Civ3. You can see what I mean by clicking here.
  • At the start of the game, you do not start with a Worker unit as in Civ3. You must build your first one at the time of your own choosing. Note that whenever building a Settler or Worker, these units both use Hammers and Excess food to be built instead of Hammers only. The city also does not grow during this period, and when either of the units is complete, the city size does not shrink like it used to in Civilization III.
• The Civilopedia is now available from the main menu of the game for easy access.
• The general layout of the interface is this:
  The Mini-Map is on the bottom-right corner, unit statistics are on the bottom-left side, unit control and buttons are on the bottom center of the screen. On the top-right, we see a “?” sign (which indicates the Civilopedia. The Civilopedia is like the game’s manual. It includes all available information on the game) as well as the year and era. Technological research are located on the top, in the center. And finally the scientific research rate buttons are on the top-left side. On the same side, you can also find your income and Gold Per Turn (or “GPT”). There also appear to be landscape characteristics on the bottom-left side. This most likely appears as the player rolls over the terrain with the mouse. Here is a screenshot of the lower portion of the interface only. For City interface information, click here.
  
  
  • The classic unit controls such as Disband, Fortify, Explore and Sentry also appear to be on the center of the screen at the bottom. There are a few more, but we do not know what they do at this point.
  • The main Interface can also be collapsed so the player only sees the unit buttons/controls/promotions on the very bottom of your screen. You can see this in the GameSpot Game-play Footage 3 video.
  • Also in the same video you can see all the Civilopedia Sections. The sections are: Technologies, Units, Buildings, Resources, Improvements, Promotions, Unit Categories (such as Melee), Civilizations, Leaders, Religions, Civics, Projects, and finally Game Concepts.
• In Civilization IV you can left click on a unit, and then right click on the tile you’d like that unit to go.
  This is very different compared to Civilization III.
• Advisor screens: depending on which you open, you can see where all of your units are on a global map, or look at raw statistics like the average life expectancy of your people (versus the world average), your gross national product or approval rating.
• A more streamlined and intuitive interface should be familiar to any RTS player. This is one feature that will make the franchise more accessible and in line with PC gaming trends. In general, theinterface and help screens are more modern, improved, and easier to use.
  • Many tool-tips and pop-up help features are available (such as the terrain characteristics I explained just above, and the ones you can see in the screenshot). Firaxis feels you should be able to play from the main map, and use other screens only if you are a true power user. All this is aimed at getting new players off and playing as quickly as possible. Again, this is the “what-you-see-is-what-you-get” concept. Below, in the next section, you will see that this concept is carried onto the Terrain Improvements as well.They will basically animate if a citizen is working that tile.
  • Sid Meier’s Tips on tool-tips (such as Units and Technologies) are included. This option can of course be turned off via the preferences screen. The preferences screen also allows the player to enable Single-Unit graphics instead of Multi-Unit graphics.
  • Numerous Advisor pop-ups also appear during the game which will recommend to you to build a certain building in a particular city or town. You can disable these if they are unneeded to you or become too annoying.
  • The game will prompt you to construct improvements if it sees an opportunity or it feels that you’ve missed an opportunity.
• Playing the game either with a keyboard only or mouse only is easy (or you can of course use the two combined).
• By default you’ll be moving units with the right mouse button. However in the preferences section, you can change that so you can move units with the left mouse button and have a right-click menu when clicking the right.
• Wide-Screen resolutions are supported (as well as any other resolution you might be running your PC on. Civ4 also supports Dual-Monitor play. The game has to be in windowed mode and you have to give it a resolution which covers both screens.
• Hot-Key commands: Just about 100.
• City information such as its buildings, and workforce is now all accessible from the main screen. You are able to see what a city is building as well, including what state of religion it is in (although Cities can have more than one religion). To the right is an example of Shanghai building a Market. It is also Buddhist (as the icon above the city name displays).
• Adjusting what you want to displayed on the map is easy. This includes city names and sizes. You can limit everything to a maximum and allow only Units, Cities (with no names), and Roads to be displayed. You can also turn on an option to display the properties of different tiles, you will also be able to turn on a resource plot location feature, mentioned here.

Landscape Characteristics

To expand your empire, first you would need as much detail about the terrain as possible.

• More tile/terrain improvements areincluded (each resource has its own specific improvement). Pastures, Wineries, Watermills, Windmills, Lumber Mills, Mines,

  Fishing Nets, Offshore

  Platforms,

  and Factories
  are all represented in detail on

  the terrain. 20 improvements in all are going to be included. Improvements being worked on with citizens will animate,

  which makes it convenient

  to see

  where your citizens are working. For example, if a Mine is being worked on by
  a citizen, you will see smoke coming out of its chimney.
  Details such as mine carts being pushed out of a mine are also available.
  This interface feature even helps you during war time, allowing the player
  to see which tile an enemy is using. Certain Technologies will make some

  improvements more productive as well.

• Roads and Rail-Roads will only provide a movement bonus
  to your units and nothing else. This has been done so the player does not have Roads and Rail-Roads on every tile later on
  (unlike in Civilization III).

  Tribal Village	Provides bonuses such as more experience points for the unit that uncovered it, maps, technologies, etc. (Goody Huts, or Tribal Villages, cannot be built by the player.)
  City Ruins	Sites of razed cities remain on the map (when you first capture a city, you may raze it, however this can be turned off so there is no city razing).
  Worked Tile	Worked tiles have their own animations and icons. For example, if a Quarry is worked, the crane will move. If it is not, the crane will not move.

• There are many new resources. When you are zoomed out to
  the Global View, resources areclearly marked for easy identification if you choose to mark them.
• There is less restriction when it comes to resources. Firaxis will probably give players something tosynthesize Oil, and Gunpowder

  units

  no longer

  require saltpeter.

• All resources, including food ones are tradable. Food resources will help your city’s health status.
  • Securing the seven types of food resources can also lead your
    cities to become more healthy, as they represent nutritional variety. Each
    different food resource decreases your unhealthy population by one.
• Better resource balance: Since Python Scripts are used to generate random maps, resource placement can befine-tuned. This means

  that a

  resource of
  one group cannot be a certain distance from a resource from the same group (comparing
  luxury with luxury, food with food, strategic with strategic).
  The Civ3 dilemma where one faction gets more resources than another seems to be gone. Resource migration will also

  not happen

  anymore.

• Trading is established automatically when you make deals. Rivers are like roads in Civ4 (in terms of their trade potential), so if two cities are on one river, they are

  connected and no road is needed to establish the particular trade network.

  • Due to the expanded aspect of tradinginvolving Rivers (making them like roads in terms of connectivity), City placement in
    Civ4 is made much more strategic. If a

    river connects to a lake, then a worker is able to build a road to the lake and expand the Civilization’s Trade

    Network.

• Defensive bonuses will now only be generated on Forests, Hills, and Jungles.

Victory or Defeat?

It all comes down to this: Achieving it against the AI earns you ego. Achieving it against another player earns you

respect.

• There are a lot more difficulty levels than in previous Civilization games.
  Settler, Chieftain, Warlord, Noble, Prince, Monarch, Emperor, Immortal, and
  Deity are the available difficulties now.
• The length of games is reduced from 540 turns (as in Civilization III) to 430. You are able to start in any era you wish
  (Ancient, Classical, Medieval, Industrial, Modern, Future. You start with a
  different amounts of units in each era, you will have more population in
  newly founded cities, as well as a few more buildings). Later era starts will give you larger starting cities, more

  settlers, and of course

  more techs. They will also have some limitation – earlier wonders and buildings may not be available. The developers

  are also constantly working to even out the pace of the game, hence the speed options described below.

  • There are four game speeds: Quick (mostly for Multiplayer, in Single Player mode (orSP) it is equal to

    Civ3‘s Accelerated Production mode), Medium (a bit faster than Civ3,
    15-20 hours of game-play), Epic (around 600 turns) and Marathon (introduced
    in patch v1.52). All of the game speeds (Quick, Normal, and Epic) retain all the flavor of Civ itself. So even
    though the speed is different, the feel will not change.

  • The different speeds of the game (Quick, Normal, and Epic) will
    have their Technology costs, Unit production costs, and Building appropriately tuned for the appropriate speed of thegame.
  • The game still spans from 4000BC to 2050AD. That means you have 6,050 years to achieve one of the victoriesbelow.
  • Civilization IV seems to have struck the balance between explored land and years passed. What this meansis that no longer will

    you have the entire world explored by 400AD. This, by the way, is the same for all three speeds (Quick, Medium, &

    Epic).

• Most of the victory conditions have not changed from Civ3.
  Here they are:
  • The Time Victory: One can win this by having the highest score at 2050.
  • The Conquest Victory: By eliminating all rival Civilizations, you have achieved this victory.
  • The Domination Victory: This is awarded when you have a 25% lead in population over their best competitor, and65% of the global landmass.
  • The Cultural Victory: You can achieve this by having three cities with a
    50,000-point Culture rating.
  • The Spaceship Victory: Having first built all the components of a Space Ship and launching it to AlphaCentauri, earns you thisvictory.
  • The Diplomatic Victory: After building the United Nations Great Wonder, your Civilization is voted on to takecontrol over thatorganization. Since it is

    difficult to maintain good relations with all Civilizations (especially in large games), this is possibly the most

    difficult
    victory condition to achieve.

    Click on the United Nations link for more information
    on that wonder.

• Winning the game also gives you a movie (no matter how you chose to win it).
• The Spaceship (which is required for this) contains about a dozen componentstotal. Some of the parts are: SS Casing, SS Cockpit, SS Docking Bay, SS Engine,
  SS Life Support, SS Stasis Chamber, and the SS Thrusters. You may boost production on this by constructing Laboratories inyour cities or by

  construction the Space Elevator Great Wonder, which boosts Spaceship
  part

  production in all of your cities.

• The game will calculate a running score for each Civilization. This is based on
  the following details: Civilization size, technology, military power, and more. Ifyou leave your Civilization lightly defended or with obsolete units, other nations will take advantage of this.
• There is still a replay at the end of the game (when it is won or lost), and after each game the replays are savedso you can later viewthem in the “Hall of

  Fame” and look at how well you did in different games. They show things such as the appearance of Great People, City

  foundations, Civs being
  wiped out, etc. The Hall of Fame screen not only remembers every game’s
  statistic under your profile (you can create different profiles in Civ4). It
  remembers Difficulty Level, Game Speed, Victory Achieved, Starting Era,
  World Size, Finish Date, as well as the Score Itself and more. It also saves
  every game’s replay so you can look back to any previous game which you have
  finished and watch how you developed. The score, by the way, is broken down
  in a detailed manner in-game as you move your mouse cursor over your name
  (the score is broken down to Population, Land, Technologies, Wonders, etc).
  These can also be saved separately from a regular game save and you can send
  these to other people.

The 18 Civilizations

There are a lot of opportunities in the game to form allies, and that is necessary to fend off enemies.

• • 18 playable Civilizations are featured in Civilization IV.
    • There are 26 world leaders. Choosing between two leaders for a
      Civilization is a possibility. You can choose from two leaders from each Civilization, however not every Civilizationhas

      two leaders.

    • You can name the leaders after yourself, and
      pretty much name everything else throughout the game…
  • Unique Units for each Civilization are still in the game. Some of
    the known Unique Units (or “UUs”) are below in the Civilization Chart.
  • You are able to see more of the leaders bodies, unlike in
    Civilization III, where one could not see them make hand and finger movements. Anexample of this can be seen when watching the “Game-Play

    Footage 2″ video at GameSpot. Leader animations will also reflect their mood and natural personality.

    • Anoffer in
      the favor of Louis XIV or Hatshepsut will show animations of the leaders that suggest their happiness with the deal. They

      will simply act

      pleased.
      However some rulers are a bit more inscrutable. The only difference in personality you will see in the Chinese ruler, Qin

      Shi Haug is the

      elevation
      of his eyebrows… the same as the Mongol leader Genghis Khan. Rulers like
      Alexander the Great of the Greeks and Julius Caesar of the Romans are much
      more expressive in their emotions. Julius will give you a gladiatorial
      thumbs-up or thumbs-down in reaction to your proposal. Gandhi is generous
      to weaker nations, while Genghis Khan will shy away from any diplomacy at all.
      Basically, there are a variety of unique personalities, some warlike,
      peaceful, trustworthy, etc. You can also select Random Personalities at the
      start of the game so every leader acts differently than what they usually do.

  • Units of different nationalities can now share tiles. If you have open borders with a Civilization, your units canliterally go to any

    tile (even in Cities!).

  • All the known
    Civilization properties have been listed below. Each
    Leader has two Traits. Each of these grants them a unique bonus and cuts the
    cost of two city improvements by half. Here are the statistics, and both of
    the following charts are brand new:

    Trait	Benefit
    Aggressive	Free Combat I promotion of melee and gunpowder units. Double production speed of Barracks and Drydock.
    Creative	+2 culture per city. Double production speed of Theater, Coliseum.
    Expansive	+2 health per city. Double production speed of granary and harbor.
    Financial	+1 commerce on plots with 2 commerce. Double production speed of Bank.
    Industrious	Wonder production increased 50 percent. Double production speed of Forge.
    Organized	Civic upkeep reduced 50 percent. Double production speed of lighthouse and courthouse.
    Philosophical	Great People birth rate increased 100 percent. Double production speed of University.
    Spiritual	No anarchy. Double production speed of the Temple.

• Barbarians in Civilization IV are not able to develop a full culture
  like the main 18 competing Civilizations, however you will see them forming
  independent cities and small militias. They are like a “mini-Civ” that can cause trouble at any time.
• Barbarians may also capture and control your cities as well as the obvious pillaging of your improvements if you find them in your territory.
  • Animal attackers (which pose a similar threat as Barbarians do), such as Lions, Bears, Jaguars and wolves
    are present early on in thegame.

Artificial Intelligence

Perhaps a significant component of good game-play is a good AI. The AI is much improved in the new game…

• Improving the AI has been a large priority. For months now, much focus has been dedicated to it.
• The AI now seems to be blind. It does not know where certain things appear (unlike in Civilization III. Onhigher levels, the AI

  still
  receives production bonuses. In the end, rest assured, you are playing against a smarter AI, not a more cheating

  one.

• The AI is more interactive and it will contact you much more often for various things in its interest.
• The AI will no longer attack in a few huge stacks of units. Instead you will now see the AI attacking in steadywaves of units that just

  keep coming!

• The AI attitudes toward you can be either Friendly, Pleased, Cautious, Annoyed, or Furious). This the reasons forthis are, again, very

  clearly laid out in the diplomacy window.

• Selecting AI Random Personalities is also a possibility at the start of the game. This way, you do not knowhow the AI will behave

  (Gandhi may not always be
  polite, and Genghis Khan may not be warlike!).

• The City Governor AI will also be more improved to assist you better. And that is an important part, becauseit naturally allows

  you to

  micro-manage less. And another main goal of Firaxis is to kill player micro-management.

• 
  When in the
  Bargaining Table, you can now see why the leader’s
  attitude is the way it is. Here is a positive point in the relationship and attitude: “+1 Years of peace havestrengthened our

  relationship.” Here are also a few negative
  points which may occur: “-1 Our close borders spark tension,” “-3 We are upset that you have fallen

  under the sway of a

  heathen religion,” “-1

  You have traded with our worst enemies!” These can be seen here.
  Basically, the positive points are: If you have the same religion with that
  Civ, similar Civics, resource trading, fair trade relations, years of peace.
  The negative points may be: If you have a different religion than that Civ, if
  you have traded with an enemy of that Civ, closed borders (they spark
  tension), refuse to stop trading with a certain Civ. Different leaders will place different weights on these factors.
  There are true hard feelings in this system, and it is much harder to simply
  bribe an AI in diplomacy in order to make it do what you want it to do.

• The game is sped up thanks to faster AI moves during the
  Middle and Late stages of the game. Some features tended to slow down the late game.
  They have been removed (for example: pollution cleanup, city riots, and units disbanding due to money issues). This meansthe late game
  is just as

  enjoyable
  to play as the rest of the game.

International Affairs

Above, the AI and Diplomacy virtually go hand in hand. Both are also improved… which means a much more

powerful

system.

• The AI must respect your borders or declare war in
  Civilization IV. AI’s did not have to respect your border at all in
  previous Civilization titles. Look back at any game and most players will see frustration of how the AIkept wondering around in your own border, without you being able to do anything
  about it.
• If you have a Defensive Pact with someone, and they get attacked, you will have the option to back down andnot get involved in

  that war. This will
  of course damage your reputation, but remember that in Civ3 you absolutely had to get into a war
  no matter what.

• Negotiating peace in diplomacy is now possible between two Civilizations which are at war with each other.On the other hand, it

  is also

  possible to make two other Civilizations go to war, even if you do not wish to get involved at all.

• Your military still plays a large role in Civ4 however it has been balanced out with other options,such as diplomacy. A

  lot of
  emphasis has been put in in balancing different aspects of the game so the player does not focus on one
  aspect more than on another.

• Trading made easy: There is a new screen that explainswhat other Civilizations have to offer and what they want to trade for (it also
  tells you what technologies and resources the AIs have). This is all in the
  foreign advisor screen. This screen also tells you the AI relations toward
  you, current ongoing deals, etc.
• The player may gift units to the AI by moving a unit in their territory and pressing the “Gift” button whichautomatically makes that unit

  theirs.

• The diplomatic victory condition is triggered by construction of the United Nationsgreat wonder. When it is

  first constructed, a Secretary General is

  elected (every Civilization gets a vote during this. The builder of this does
  not automatically get to be the secretary General). If you get elected, you can get various resolutions passed.
  Here they are:

  • Free Trade – Free Trade removes all trading restrictions in the world between allCivilizations. It

    basically functions as if all Civilizations have open borders – No matter what their real diplomatic relationship may

    be.

  • Nuclear Non-Proliferation – As Thunderfall’s article has mentioned already, adopting this means that no nukes may be built, howeverexisting nuclear weapons

    are not destroyed. Note that if this resolution passes before any nuke is built in the world, it means that the game itself

    will proceed without

    nukes appearing. This may be a benefit to you if you’re playing against aggressive Civilizations.

  • Universal Suffrage – All Civilization’s civics are changed to Universal Suffrage (+1Hammer from Town; Can

    spend gold to finish production) no matter if they have the required technology for that specific Civic (this counts for

    all UN Resolutions

    relating to Civics).

  • Free Speech – All Civilizations adopt the Free Speech Civic (100% culture
    in all cities; +2 gold from Town).
  • Emancipation – All Civilizations switch to the Emancipation Civic ((100%
    Growth for Cottage, Hamlet, Village; Unhappiness for civs without that civic).
  • Environmentalism – All Civilizations adopt the Environmentalism Civic
    ((+6 health in all cities; +1 happiness from jungle, forest).
  • And finally, Free Religion – All Civilizations Adopt this Civic (No
    non-state religion spread; +1 happiness per non-state religion in a city, +10%
    science in all cities).

  If you fail to get elected, you have to wait until the next election. You can use the UN as a diplomatic

  tool to force other nations to adopt certain policies which they normally wouldn’t.
  Note that after every three resolutions, a new Secretary General is up for
  election.

• Building Spy units is possible just like in Civilization II (they
  now have a movement of two and cost 80 Hammers).
  The player is limited to the number of Spies you can have in the game. Before
  construction the player must have the following: Communism and the Scotland Yard
  National Wonder, meaning every Civilization may build its own (500 Hammers; +1
  Great People Points; More likely to generate a Great Scientist). You are allowed
  to have a maximum of four spies at any one time. They are invisible to other
  Civilizations just like Submarines. These units cannot be attacked or interacted
  with, however they can be exposed by rival Spies (you are able to expose enemy
  Spies as well). Other abilities of the Spy unit include:
  • Investigate City – This is rather basic. It allows you to have a peek inside anenemy city and see all

    its properties (what it is producing, Culture
    amount, what unit it has, etc, etc).

  • Destroy Production – If you order your Spy to destroy the production of whatever a cityis producing (and if

    successful), half of whatever is being produced
    is destroyed (therefore slowing down dramatically production of, say, a Great Wonder). However, if the Spy fails, it is

    killed.

  • Sabotage Improvement – If a Spy is ordered to do so, and if successful, a terrainimprovement will be

    destroyed (such as a valuable Oil Well). If
    unsuccessful, the Spy will be destroyed.

  • Steal Plans – First of all, the Spy has a much better chance of having success at thisif the action is

    taking place in a City which contains either a
    Palace (therefore the capitol of that Civilization), a Forbidden Palace, or the Versailles Great Wonder (Requires Divine

    Right; Reduces

    Maintenance in nearby
    cities; City in which it is built in is more likely to generate a Great Merchant; Doubled Production speed with the Marble

    resource).

  The above actions need gold. Success depends on the amount of units the other Civilization has in the area of where the

  action is taking place.

  Nearby enemy spies
  also decrease the amount of success your Spy unit has.

• Other Civilizations have different favored Government and Religious settings, and they will try to pressure players into changing to their favored religion or government to suit their

  desires in return for better relations with your Civilization.
  They can even ask you to stop using a Civics option you have set.

  • Leaders will appreciate other leaders that share
    their traits and civic or religious choices (as stated above), and they will tend to form blocs. If you find leaders thatshare your tendencies,

    it will be

    possible to form lasting
    (even permanent) alliances.

  • What you choose might affect other Civilizations as well. If you have already introduced Emancipation, it sometimesmay lead to

    unhappiness and

    revolts
    within other nations without Emancipation, but to you, it does not give a direct benefit (so it provides a negative aspect

    to other Civs, if they

    don’t have

    it).
    Also, if your Civilization is the first to outlaw slavery, that will create discontent in societies that have

    slavery.

• In diplomacy you can try to make another civ adopt a certain Civic or a Religion that you have. However the AIs aremuch more focused on

  their own agenda.

  Some Civs care more of your type of religion, others care more about your Civics, others follow whoever has the most money.

  AI Civilizations can

  even call up

  the human player and ask him/her to stop trading with a Civilization they hate. This make the player make decisions which

  impact relations a

  great deal.

• Filling in the blanks: You can put a deal on the table and then ask the AI
  leader to fill in the blanks, no matter what combination is out there. You can also tell when a deal would never happenbecause the choices will

  show up in

  red on
  the list. On a related AI note, Soren Johnson (the Lead Designer for the game) is now totally focused on tweaking the

  AI.

Controlling Your People… by Decree

All the power is in your hands. What you do with it can lead to your Empire’s victory or your utter demise.

• World Religion, Civics and Great People are things many people have suggested be put into the game, Soren has described these

  as
  “killer” features in his PowerPoint. These are in Civ4, and they will have an influence on your whole

  empire. The factors

  which have

  a

  domestic affect are described below…

• Factors which are not fun in the game such as corruption/waste, rioting, pollution, and maintenance
  are started from scratch or removed(this means that they are replaced by a much better concept that maintains game
  balance better). Pollution is most affected. It was dumped,

  although not completely removed. A more extensive health system is something new, although no details about it have

  surfaced yet. Annoying

  micromanagement tasks will also be decreasing dramatically, and more high-level control
  is provided.

  • The concept of corruption has beenreplaced with
    maintenance costs. This time instead of Courthouses being able to reduce corruption (since it is gone) they will actually

    lower
    maintenance costs.

• 
  You will have to develop your culture or risk being enveloped by a larger neighbor (so a nationcan be completely

  engulfed by another’s

  borders).

  • The luxury slider is now a culture slider. The more culture you give, the happier your people will be, as well asproducing more culture

    for

    your entire Civilization, meaning it can also expand your borders more, the more
    you increase it (but at the expense of Commerce and Science Research).

  • Culture basically modifies your borders in relation to the culture of your neighbors, so you can overwhelm yourneighbors with a

    superior

    culture.

  • Culture now also increases a citys defensive value, and it helps smaller cities with more culture feel safer. Sinceit restarts when you

    capture a city, your top priority is to maximize culture in that city.

  • There is no more Cultural Dominance in flipping Cities. Instead, as your nation expands, foreign cities will beginto become more and more

    in

    awe with your Civilization as a whole. This will cause the people in those foreign cities to get unhappy, and therefore

    their Civilization will

    have to

    spend money to keep them happy. As this burden gets heavier, that Civilization might just offer to give you their Cities

    via diplomacy.
    One easy way to counter unrest in your cities due to your neighbors having
    superior culture is to station more units into that city.

  • Culture essentially represents a “Soft Power.” This means that nations can defeat other nations through morepeaceful

    means.

• Health is just as important as maintaining your treasury and the happiness of your people. Health
  is tied to available food andresources to simulate Epidemics. However, if you have Fresh Water near you, it will give you a health

  benefit.

• There is a lot of built-in automation in the game (also aimed at reducing micromanagement). Setting units such asthe Warrior to “Auto

  Explore” and find

  “Goody Huts” (which give you free bonuses such as a Settler, or something else) is a great idea.

• Thanks to automation, when a Worker is available, the player is able to automate the worker and let the artificialintelligence take

  control of it. The

  worker will then build the best available option on each square, as well as link your cities together by roads.
  This improves the pace of the game immensely and is a very efficient process, since you don’t have to worry about manually

  moving the worker (you

  can do that

  still, however).

• Variety in food can improve your citizens moods making them happier. Entertainers are also available,spending tax dollars to

  buy their

  happiness and city improvements.

• In total, there are 25 Civics options. There are five categories and five options per each category. The fivecategories are:

  Government,

  Legal, Labor, Economy, and Religion. Some of the known Civics options are: Free Market, Environment, Slavery, Free Speech,

  Conscription,

  Emancipation,

  Religious Tolerance and the Nationhood (it magnifies culture accumulation). Below is a table of how you will see your

  Government system in the

  game. Having all these choices means that you will not have “fixed” governments
  anymore (simply known as Democracy, Communism, etc in Civ3). Note
  that Civics choices have an upkeep cost (depending on the Civic).

  • Changing to new Civic forms will have a dramatic effect on the character and success of your civilization.You’ll be able to boost

    or cut
    productivity, wealth, and happiness, make choices to increase/decrease the spread of religion, and even affect your

    ability to produce and

    maintain a
    large standing army. It is also never as simple as choosing the only the
    highest levels in the Civics section. “…You could end up with a really
    great government that puts you in the poorhouse,” says

    Barry.

    Government	Legal	Labor	Economy	Religion
    Despotism: Low Upkeep	Barbarism: Low Upkeep	Tribalism: Low Upkeep	Decentralization: Low Upkeep	Paganism: Low Upkeep
    Hereditary Rule: +1 happiness per military unit in city. Medium Upkeep. Required Tech: Monarchy	Vassalage: New Units receive +2 Experience Points. Lower unit support cost. High Upkeep.  Required Tech: Feudalism	Slavery: May use population to rush production in a city. No Upkeep. Required Tech: Bronze Working	Mercantilism: +1 Free specialist per city. Noforeign trade routes. Medium Upkeep. Required Tech: Banking	Organized Religion: Can build Missionaries without a Monastery. Cities with state religion construct buildings 25% faster. High Upkeep. Required Tech: Monotheism
    Representation:+3 Science per specialist, +3 happiness in top 5 largest cities. Low Upkeep. Required Tech: Constitution	Bureaucracy: +50% hammers, +50% commerce in Capitol City. Medium Upkeep. Required Tech: Civil Service	Serfdom: +50% Worker build rate. Low Upkeep. Required Tech: Feudalism	Free Market: +1 trade route per city; Low Upkeep. Required Tech: Economics	Theocracy: +2 experience points in cities with state religion. No non-state religion spread. Medium Upkeep.  Required Tech: Theology

Low Upkeep.Required Tech: Nationalism	Caste System: Unlimited Artist, Scientist, and Merchant in cities. Medium Upkeep. Required Tech: Code of Laws	State Property: -100% maintenance costs from distance to Palace/Capitol City. +1 food from Workshop and Watermill. No Upkeep. Required Tech: Communism	Pacifism: +100% Great People birth rate. +1 gold support cost per military unit. No Upkeep. Required Tech: Philosophy
    Universal Suffrage: +1 hammer from Town. May spend gold to finish production. Medium Upkeep. Required Tech: Democracy	Free Speech: +100% culture in all cities, +2 gold from Town. Low Upkeep. Required Tech: Liberalism	Emancipation: +100% growth for Cottage, Hamlet, Village. Unhappiness penalty for civilizations without Emancipation. Required Tech: Democracy	Environmentalism: +6 health in all cities. +1 happiness from Jungle and Forest. Medium Upkeep. Required Tech: Medicine	Free Religion: No non-state religion spread. +1 happiness per non-state religion in a city. +10% science research inall cities. LowUpkeep. Required Tech: Liberalism

• When you are at peace,
  Free Markets, Emancipation, and Representation are fine choices as Civic options. During war, you can select Civic choiceswhich are

  better suited for that situation (which may mean that your units are not as expensive to maintain, and therefore you can

  have a larger army). Of

  course, to

  prevent you from switching back and fourth, there will be a temporary anarchy period between Civic choices if

  switching.

A New Aspect: Religion

All

religions in the game are equal. However they also have an impact on diplomacy.
“It’s like culture without borders,” as Jesse Smith Puts it.

• State Religions can be declared by any Civilization. You can also switch this, but you will go through aperiod of anarchy,

  just like when
  switching the state of your government. Declaring a State Religion means that all cities in the Civilization with the same

  religion get extra
  happiness and produce more gold. The default to no-state religion is Paganism,
  which means there is no organized religion.

• Founding a Religion is done when a Civilization discovers a
  technology that is linked to a certain religion. Afterwards, a Holy City is
  established. When a Religion is established in a city, it will gradually spread from there.
  • When a City has a religion whichdiffers from the State Religion of the Civilization, the citizens in that city may become unhappy and eager to
    adapt the state religion.
  • Since cities which are not in the Civilization’s state religion do not share the happiness and commerce bonus,it is a good strategy

    for you

    to
    spread an unofficial religion. However, spreading too many religions to one Civilization is not always a wise tactic, The

    Freedom of Religion
    Civics option grants bonuses to civilizations which have many different religions.

  • You can see which State Religion of another Civilization you have made contact with by checking the small leaderboard in the

    lower-Right

    corner of
    the game screen.

  • Like what has already been mentioned before in prior updates, the first Civilization to discover a
    technology that enables a religion will be
    assigned a Holy City. Owning a Holy City gives you a line of sight for all cities in the world that share that religion,and therefore

    encouraging
    you to spread to spread your faith even more around the world. In the Holy City you can also build Great Wonders that have

    the ability to improve
    the happiness of people throughout your empire. Holy Cities are assigned to the AI by random, but most likely near the

    center of the empire, or

    the
    capitol of the empire.

• Not only will you see Wonder Movies (CGI Cutscenes showing the construction of a wonder), but you will alsosee a movie each time

  you discover a religion. Winning the game also gives you a wonder movie (no matter how you chose to win it).

• Every temple in the world dedicated toa religion
  will generate gold which will go to that religion’s Holy City. This makes it
  even more worth it to try and convert other cities around the world to your
  State Religion.
• Conquered people who have a different religion than your state religion will naturally be pretty unhappy. Inlater eras you can

  research

  technology to mitigate these effects, but religion now has to factor into your overall strategy.

• Seven real-world Religions are available in the game. There is also a special unit
  for all Religions: the Missionary. Below is a helpful chart of the religions in the game, and theirreal-life significance:

  Religion		First to Discover	Wonder & Buildings
  Buddhism		Meditation	The Mahabodhi; BuddhistMonastery, Buddhist Stupa, Buddhist Temple
  Christianity		Theology	The Church of the Nativity; Christian Cathedral, Christian Monastery, ChristianTemple
  Confucianism		Code of Laws	The Kong Miao; ConfucianAcademy, Confucian Monastery, Confucian Temple
  Hinduism		Polytheism	The Kashi Wishwanath; HinduMandir, Hindu Monastery, Hindu Temple
  Islam		Divine Right	The Masjid Al-Haram; Islamic Monastery, Islamic Mosque, Islamic Temple
  Judaism		Monotheism	The Temple of Solomon; Jewish Monastery, Jewish Synagogue, Jewish Temple
  Taoism		Philosophy	The Dai Miao; Taoist Monastery,Taoist Pagoda, Taoist Temple

  • The Missionary may be sent out to try to convert other cities to your religion. Just like Civics, AIs will tryto convert you to their

    religion the same way.

  • If you are successful in a city, you will also receive a line of
    sight bonus and if you capture or control the main holy city of each
    religion, you get line of sights in each city in the world that has that
    religion.
  • To keep your civilization’s religion strong, you must constantly be building religious buildings and pushingyour own Missionaries to

    convert foreign cities. If you do not want foreign Missionaries to enter your lands, simply do not sign open borders.
    The only other time Missionaries can enter your borders are when a
    Civilization declares war on you.

  • While Closed Borders mean that other missionaries cannot enter your lands and spread their religion, it alsomeans that you

    will not be able to trade with other Civilizations.

  • Success in spreading your State Religion to the AI will lead to
    better relations.
• Religions will not have bonuses (most likely the developers like to keep everything perfectly balancedbecause it is a touchy

  subject), but

  they will impact diplomacy. If you ally yourself with a Civilization with the same religion as

  yours, it will enable
  you to curry favor with other like-minded peoples. However, they come
  with a memory, if you suddenly switch to their religion, they will not
  be as inclined to cooperate with you. You will need to be in their
  religion for a significant amount of time.

The Influence of Great People

Great

People also add a great deal of variety to the game. Some offer extremely great benefits as we’ll cover below…

• There are five categories of Great People:
  Great Artist, Great Merchantman, Great Prophet, Great Engineer, and Great Scientists. All of them have a movement oftwo, and are invisible

  to other

  units. These will probably

  be triggered by City performance, therefore, they cannot be built. Each will also have three to four benefits, including

  culture boost,
  Academies
  (created by Great Scientists),

  multiple
  Golden Ages (when having two different Great People), and free techs, as well as wonder construction and city output.
  Please look at the first chart below for more details on their ability and
  historic figure.

  • Great People are easier to get inCivilization IV, and they
    will also be the only way a player can spark a Golden Age other than by constructing a particular Great Wonder.
    (Please see the chart below for more information on what exactly is required
    for a Golden Age when having available Great People.)
  • A Golden Age means that you get a boost in production and happiness (a
    Golden Age also lasts for eight (8) turns). Again, you can also have multiple Golden Ages (each subsequent golden agewill
    require more Great People) unlike in Civilization

    III, where you were allowed only one.

• You can get great leaders by specialized cities. You can customize each city to fit a specific purpose suchas science or culture.

  Great

  engineers will allow you to rush production on a wonder,
  or other building and naturally, they may only be used once, so it shouldn’t come as a surprise.
  A Great Merchant may let you establish an extremely

  lucrative trade deal (meaning you will get a large boost in your treasury), or a
  Great Scientist will significantly boost your research
  or create an Academy. Look below in the chart for much more details on this.
  Also you may want to check out the Cities section for more information on
  specialization.

• You can generate more “Great People” points
  by taking city population away from working the land and turning them into specialists. Also, certain civics choices areable to make your

  specialists more
  productive and that can also have a positive effect on your “Great People” point production.

  • For all but one (the Great Prophet), there are ancient and modern representations of the unit.
• Great People can be turned into “Super Citizens” where they can give a city an ongoing bonus
  for a period of time, or they can be used to give your Civilizationa large one-time bonus. Below is a detailed list of the Great People, how they can be used, and the historic figures they

  might represent:

  Great Person	Benefits
  Great Artist(Emphasis on Culture)	Has the potential to trigger a Golden Age (or GA). Requires two Great People for the first GA*. Can join a city and produce +3 gold and +12 culture per turn. Producing a “Great Work” grants the city 4,000 culture points automatically. (Labeled as the “Culture Bomb”). They can discover a Cultural-Related Technology, for example, Literature.
  Great Engineer (Emphasis on Production)	Has the potential to trigger a Golden Age. Requires two Great People for the first GA*. Can join a city and produce +3 hammers and +3 science per turn. May rush production, like a Great Wonder. Can discover an Engineering-Related Technology
  Great Merchant (Emphasis on Wealth)	Has the potential to trigger a Golden Age. Requires two Great People for the first GA*. Can join a city and produce +1 food and +6 gold each turn. Can establish a one-time trade mission for 1000~ gold. Can discover a Commercially-Related Technology, like Banking.
  Great Prophet (Emphasis on Religion)	Has the potential to trigger a Golden Age. Requires two Great People for the first GA*. May join a city and produce +2 hammers and +5 gold per turn. May build one Shrine/per religion, in the city of the founded religion. Can discover a Religious-Related Technology
  Great Scientist (Emphasis on Science)	Has the potential to trigger a Golden Age. Requires two Great People for the first GA*. May join a city and produce +1 hammer and +6 science. May create an Academy (boost of Science and Culture) in a city. Can discover a Scientific-Related Technology.
  * With each Golden Age Requiring more Great People… For more information on the other units, go here.

City Essentials

Cities are like the many hearts of your Civilization. If you take care of them, they are bound to take care of

you.

• • Instead of shields, youll see hammers. The more you have, the
    faster you build units, buildings, etc. The amount you have is determined by
    the terrain, and improvements
    • There is some sort of Hammer/Beaker rollover (Hammers mean production,
      and Beakers mean Technology research as said before).
    • When viewing the City Screen, a bag ofmoney = 5 gold,
      an anvil = 5 hammers, and a loaf of bread = 5 food.
  • City Specialists: The number of city specialists are limited.
    However, with the “Caste System” civic you may have unlimited city
    specialists. Even though specialists provide bonuses to your cities, they do
    consume food (just like unhappy citizens, which don’t provide any bonuses at
    all). The total number of specialists are five. They are: Scientists,
    Priests, Engineers, Merchants, Artists. Citizens are the ones who actually
    work on the land and give you benefits such as food, hammers, and
    gold/commerce.
  • Drafting can occur with either spending gold, or city population.
    Naturally, this depends on your Civics choices and it will also create
    unhappiness if you do draft.
  • Before founding your first City, the User-Friendliness of the game will immediately highlight attractive tiles toestablish your first

    city, and later on,

    other cities. This feature takes into account nearby resources, terrain features and the proximity to other

    Civilizations.

  • GameSpot says that “Once you’ve

    settled down into your

    first city, the game bends over backward to be user-friendly.” Your first task after building a city
    is to select a list of offered and available

    technologies. Some of these are recommended to you before choosing them (it is very possible to ignore these

    recommendations). After selecting

    what you want

    to research, you will have to select what you want your city to build. Two of the options are recommended (just like some

    of the Technology

    Choices are). The

    recommendations are, of course, sound choices. But again, you can feel free to follow your own path.

    • Founding a second city quickly can be immensely helpful in solidifying a lead against your
      neighbor or neighbors.
  • To get more culture, in addition to the slider already described, Entertainment Specialists also help withculture generation.

    Building still

    matter, but they will just serve as cultural multipliers than producers.

  • A single city can sometimes be found with more than one religion. This usually happens when a foreign Missionaryestablishes its own

    religion in a city with

    a different established religion.

  • 
    You are not guaranteed the nine-square territory when you first build a city
    in Civilization IV. You may find a city that owns only its base tile,

    and is completely engulfed in another Civilization’s borders. To the right is an
    example of this…

  • Cities do require a maintenance amount, and with
    each city that will increase (therefore one can’t just start building Settlers and Cities right away like crazy). Eventhough this is a

    significant change,

    the
    ability to build very large empires is still there. The difference is that it requires more strategy to do so. As cities

    grow, they
    are able to sustain
    themselves better without putting too much weight on the overall economy. Naturally, using diplomacy, religion, trade

    networks, and improvements

    will

    increase
    income (and that will help fight increasing maintenance costs).

    • Cities on the outer-most fringe of your empire will still build
      relatively quickly (as there is no corruption anymore). However their maintenance cost will be higher to
      compensate for that.
    • The game is more balanced towards not having as many cities. You
      will, however, still have a broad area. The focus is to have fewer but more specialized cities.
      Also note that there is no city limit. You may build as many as you wish
      however keep note of the previous comment in the last sentence.
    • The city
      maintenance cost puts pressure on rapidly expanding
      Civilizations, when rapid expansion might not be the best choice at the time. The AI will recognize this too, and they willnot keep throwing

      settlers

      towards your
      boundaries.

  • Balancing out your priorities is the key. If you build cities too often, they will be very vulnerable.However, if you don’t build
    cities and expand fast enough, you will be left in the dust. Prioritizing between expansion, research, building military

    units, and
    improving your core cities is really essential. Reading the landscape for resources, and good city positions is also very

    important.
    Building cities on hills or on rivers will help them survive longer, and make them less vulnerable.

  • Civic improvements/buildings are shown off on the terrain, as
    well as wonders. Basically, everything that you build (other than units) is
    shown on the terrain near the city.

• Right-Clicking on a city will bringup contextual menus, which will show the player options such as build orders, and governor settings.
  Having said that, the city governor provides much more control over
  automation.
  • Information in the city itself is much clearer as well, for the players who do wish to get a more detailedpicture. Each improvement

    in the

    city
    has the specific benefits it offers to the city itself. Contentment and culture are also present in more detail. This means

    that the player will

    no
    longer have to keep looking through the Civilopedia for what certain buildings or aspects add to the game-play.

  • In order to simplify your building choice in cities, you are able to Shift-Click on a city in order to select whatyou want it to build,

    this even without entering the main city interface. It will all be on the main interface. You will also be able to set

    Build Queue orders so you

    can

    select which things you want to build in a particular order (so if you select the Archer then Temple and then the Pyramids

    in this order,

    production

    will automatically switch each time a unit/building is done).

  • Selecting multiple cities makes
    management even easier. Jesse Smith states in this Developer Interview at GameSpot that the goal is to make everything as easy for the player as possible. This allows the player to

    set the same building

    orders to a few cities at once. These features (the Build Queue and the city selection method) along with the flexibility

    of options from the

    City

    Governor make managing cities extremely easy. There are six governor options
    which will make it easy for you to customize what you want from that city.
    Emphasize food, production, commerce, science, great people, and “Stop growth.”
    These can be mixed, matched, etc, etc.

  • Setting common Rally Points to cities (or multiple
    cities via the Shift-Click method) is also possible. This allows units that have just been built to go to that selectedspot automatically

    without the

    player’s input.

  • When entering the city menu itself, you will see that older-style
    text-based menus have all been replaced with graphical icons instead. The
    uppermost part of the screen includes Scientific Research (center), Income and
    current gold amount (left), and the date (right). Also in the upper part is the
    current production (units, buildings, etc), growth rate, City name, as well as
    the defensive bonus of the city (determined by improvements as well as culture),
    health status (healthy to unhealthy citizens) as well as happiness (happy to
    unhappy citizens, this also includes the reasons the citizens are happy or
    unhappy). The top-left includes Scientific Rate,
    Culture Rate (as well as the happiness it generates), and Tax Rate (these three
    are determined as a percentage). We also can see a Maintenance Cost. On the left
    side of the City Interface is a Trade Route Bonus display (these provide gold),
    as well as what your current Buildings are. Also visible is the percentage of
    your nationality and Culture rate per turn. The bottom part is the build queue
    (Units, Improvements, or Wonders — all represented as icons), the lower-right
    part are the City Governor options as well as the Mini-Map. The Right Side of the screen we can see the current city
    religion; Luxury, Strategic, and Food resources; the city specialists are also
    on the right side, as well as the Great People accumulation points. The middle,
    of course, is the City Display. The Circled tiles represent worked tiles by your
    citizens Since a
    picture can speak a thousand words, here is a perfect example of the city
    screen.
  • Just moving the mouse over the city willproduce results such as how fast the city is growing, building status, resources collected, as well as culture and Great

    People

    information.

• No longer will you be able to transfer production from one project
  to another. This exploit has remained for a long time, and it has been addressed.
  • An example of the above bullet point is that when you lose a wonder to
    another Civilization by a few turns, you will also lose all the production made on it, therefore you will no longer be ableto transfer it to

    another project

    however you will be
    refunded a certain amount of gold. This rule is for units and other buildings as well. For example, if you switch

    production from a Settler to an

    Archer, the

    production will
    not shift to the Archer, however it will be saved for the Settler when you come back to it, and you will pick up from where

    you left

    off.

  • If someone beats you to a World Wonder, you will get a refund, mot likely in the hundreds of gold, depending on howmuch time you’ve spent

    on that wonder.
    This has been mentioned just above.

    This (the fact that you can no longer simply transfer production) makes it much harder for you to “monopolize” the Great

    Wonders. This is even

    more evident

    on the harder levels.

• Cities will no longer riot, but unhappy workers will not work. Until you address the problem, it will remainso.
• City names can also be changed by the player, as in Civ3.
• The bigger your city gets, the unhealthier it becomes. And
  that can take a toll on the population, as the city will eventually begin to starve
  (unhealthy citizens are not able to do as much work). You can combat this by building certain types of buildings, suchas

  aqueducts and
  hospitals. However improvements such as Factories tend to decrease the city’s health status.

Building Options

Strategy comes to play even more here… there are a total of 102 buildings, and each has its own benefits. It is up

to you to be the

builder

• There are a total of 102 buildings in Civilization IV,
  as mentioned above.
• Each religion has its own improvements and mini-wonders associated with it.
  These benefits of the wonders will still exist in cities that have switched
  away from that religion.

major powers: The

Wonders of

the World

• In total, there are about 28 Great Wonders (Great Wonders may
  be built by only one Civilization), and about 12 Small Wonders (every Civilizationis allowed to build these, and they are more city-specific. For example, a
  benefit of +100% science.

Your Advances

It is not the technology that matters It is how well you use it.

• The Technology Tree, just like its technologies, is smart and flexible. You will have the ability to researchdifferent things, but

  they will

  lead to the same level of technologies. It will offer unique paths to guide your empire along. There are no longer static

  eras, as in
  Civilization IIIs

  case, that is, the tech tree is not split into eras at all (although, as
  previously said, you can start in different eras). To put it simply, eras do
  not restrict your Technology choices and progress.

  • Like buildings, the player is able to switch
    from one technology to another, however that research will not get accumulated for the new technology you are switching to
    (in “Beakers,” the accumulation of technology. It is similar to “Hammers” when
    talking about production). And when you switch to the technology
    you were originally researching, you will get back where you left off. However this “banking” of resources or research islimited in terms that

    you will

    eventually
    start to lose production or research slowly over time. This change (production not carrying over to new buildings or

    technologies) has not been a

    large

    balance issue
    because both the AI and Human Players are “on a level playing field” (to quote Barry).

  • There are different ways to discover technologies, like the already
    mentioned Great People and Goody Huts.
  • You will also be allowed to skip whole branches of the Tech-Tree if you wish.
  • The direction of your research will have an impact on the kind of Great People that are born. The player is free tochoose any path

    whether it

    be all-military,
    all cultural, all-science, balanced, etc. You also dont need all the techs that connect to the one you want. A

    connection to it is all that

    is

    needed.

• Even with evenly spaced-out resources it can
  happen that in the early game a player may not always have a resource such as iron or horses. The tech-tree also balancesthat out should it

  happen. It makes

  it
  easy for the player to switch strategies and head in the direction of Gunpowder (for example).

• There is no longer a minimum amount of turns in
  which you can discover a technology (in Civ3 it was four turns minimum). This makes it easier to come back and getolder technologies you

  have not yet
  researched.

• There are 125 paths to Civ4‘s
  Future Technology. This information has been gathered from grumbler’s post here in the forums.
  Check it out for more information.
• Below are all 86 technologies in the game. This technology tree
  has been put together by CivFanatics’ Administrator, Thunderfall (taken from
  several separate screenshots). Below it are details of what each technology
  has to offer:

• Future Technology research gives you extra health and happiness, as described above. In Civ3 it is important to know that Future

  Technology did not do much for the player, and it is nice that that has improved as well.

• Every time a Technology is researched, the grandfatherly voice of Leonard Nimoy (Mr. Spock himself!) kicks in withan appropriate quote

  from history.

The Military Backbone: Units

There are many different types of units, and all have different abilities. On top of that, there are special

promotions as well. This makes

each

military unit unique.

• • Civilization IV will ship with a total of 83 units (this
    includes barbarian animal units, which the player cannot build in a regular
    unedited [via the World Builder] game. This includes domestic units such as workers, military ones (of course)and special units such as Great People.
  • Units can be upgraded by using your gold, as
    they become outdated. This is similar to the Civilization III way.
  • Unique combat animations are a priority,
    so you won’t see the same old animation for different types of units.
    • Units will also give verbal confirmation when you select them
      and give them orders, again, this will be a specific language to the
      Civilization that is chosen.
    • When a unit is victorious, a short music clip plays confirming
      the victory.
  • There are
    Medallions on top of flags units are carrying to indicate how many units are in that tile. If there are 15 units in asingle tile, there will

    be 15
    Medallions above the flag on that tile.

• Picking units out of a stack is easy so the player won’t have to repeat the picking out of a unit manydifferent times

  over.

• The longer a unit stays fortified, the more advantage it will have when defending against other units. Forexample, being fortified

  for five

  turns gives the unit its maximum defense bonus of 25%. The unit does not get an instant bonus the moment it is

  Fortified.

• “First Strike” is a system which simulates the advantages of
  ranged units such as archers. If a unit has this ability, it can make a
  “First Strike” against another unit before the combat actually begins,
  giving it an advantage.
• Workers, when captured from another Civilization, build at the
  same rate as your own workers. There is no “half-normal” effectiveness as
  was the case with Civ3.
• The game will also be using multi-unit graphics for individual units, they will also be carrying banners fortheir countrys flag

  and for

  easier

  identification. The Multi-Units represent actual hit-points. If you do not like
  to see multi units, you can turn this feature off so you see single-graphic
  units only. Below is a table of all known facts about units:

• A nuclear explosion can cause severe damage to the tile targeted and the eight adjacent tiles. You are not able toattack your own

  territory or cities with the ICBM. Everything goes through a “kill check” (buildings, units and terrain improvements).

  Buildings are either

  destroyed or come out unharmed if they pass. Units can be destroyed if the “kill check” fails or damaged or unharmed if

  they pass. Wonders, roads

  and railroads are not affected by a nuclear strike. In addition to these potential damages, radioactive fallout must be

  cleared by workers when

  the Ecology technology is researched. Otherwise the affected tiles are unworkable.

• Each time a nuke is used, the attitude of a Civ nuked goes down by 2 points (read more).Your relationship with

  other Civilizations around the world will also be negatively affected.

• The UN Nuclear Non-Proliferation Treaty bans the construction and use of all nuclear weapons, but existing nukes donot disappear. If this

  resolution passes before the Manhattan Project is complete, you will not even be able to finish that project and therefore

  no nuclear weapons

  will be built or used throughout that game.

• You can, of course, defend yourself from nukes by building the SDI Project which has a 75% chance of interceptingenemy nuclear weapons

  throughout your territory. You may also build a Bomb Shelter in cities. This reduces damage from ICBMs by 75%. Without the

  Bomb Shelter, the

  City’s population can be reduced as much as 50% by a single ICBM.

A New Combat System

How will you wage war? What new systems are involved? This is the section for the warmonger.

• 
  The battle system is something that has been ameliorated (it is like an RTS
  “rock-paper-scissors” concept). It has been made to actually encourage players to use the array of forces they

  have.

  Players are able to group units, as an interface change. For example, you can group a Settler and

  a

  Spearman, and they will always be together (unless you
  decide to re-group). Workers can be grouped together as well, and then their actions
  within that group can be queued. This has been changed so you will favor most different units, and not stick to your

  most powerful, for instance.

  • Using mixed attacks such as ground and aerial bombardments and not just on a single overwhelming stack of units(commonly known as the Stack of Doom) is highly encouraged. This brings more strategy to battles, and also makes them

    more realistic.

  • The fact that
    Artillery can attack all units in a stack forces players to spread out their forces to avoid damaging more units
    (artillery units can damage all units in a tile because of the collateral
    damage feature they have). Note that Artillery units such as catapults attack
    like normal units, although they can bombard cities and reduce their defenses.
  • The terrain also takes a large part in Combat. However, it can also be said that it is more simplified.
    The only time you will get a defensive bonus is when over hills, forests, or
    jungles.
• Great Artists may also have a military-related use to them. If you capture a city and it is rioting,dropping a Great Artist and

  giving the

  city a 1,000 point culture boost
  should quickly suppress all rioting and change the mood of the citizens in the city. The only way you could
  suppress rioting in Civ3 was to basically start building a lot of cultural buildings such as Temples and

  Libraries.

• Selecting any or all units in a given square has many shortcuts to
  it. The game determines the best attacker when you give astack attack order or the best defender when your stack is attacked.
  • Stack attack works by stacking a bunch of units and giving them
    the attack command. If you are using combined arms in that stack (a balance of defensive and offensive units), the gamewill automatically look

    at who you

    are attacking
    and who their defenders are.

  • The amount of damage a unit does to another unit is now
    out of a scale of 100, even though that’s more or less hidden from the user. The amount of damage a unit does is relativeto its different

    strengths. So now

    when a
    spearman attacks a tank, he may hit three times, but that’s only going to take off a quarter of the tank’s hit points.

    Meanwhile, a tank hitting

    a spearman

    only has to hit
    him once or twice, and he’s gone entirely.

  • To further explain the combat system: Two units of
    the same relative power will do about 20% damage per hit, so it would take five hits to kill a unit. When one unit is muchmore powerful (a tank

    for

    example), the
    more powerful unit does a higher percentage of damage than the less powerful one (a Spearman for instance). In other words,

    if both manage to hit

    three times

    in a
    battle, the Spearman would have done only around 40% damage, while the more tank would have already killed the spearman.

    However that is not all

    to the

    combat
    system. Many more calculations are going on behind the scenes that make for fewer lucky strikes, which further balance the

    system.

• In the options screen, players can turn on an option
  that will let them see bars over units so they can judge their chances of winning or losing before even entering thecombat.
• In all, Civ4 will offer about 41 different promotions for
  units (with 20 different promotion types. However some have more than one
  level, as you will see below. Units may receive up to 20 promotions as well). This allows each unit to be extremelyflexible in its

  abilities. So,

  how do units get these promotions? Well, they might get them from a battle, depending on how difficult it has been. The

  great thing about

  promotions is

  that they are not triggered by technology either. As they win, they will gather experience points.

  You will make specialized units without changing any of their previous
  specializations; you can also change their paths with certain
  situations.

  • Auto Promoting units is also an option you have. However you can always promote them manually.
  • The numbers and types of available bonuses
    differ per unit type and only land and sea military units can acquire them (air units are different).
  • There are no XPs (experience points) from bombarding
    fortifications or if the opposing unit withdraws.
  • Units can also gain experience from a Barracks
    (land units), a Drydock (sea units) or a goody hut.
  • Some wonders, civic choices, and leader traits can
    give units extra experience or even certain promotions. As you might expect, the first promotion comes rather quickly,while each subsequent

    promotion

    requires more
    XP. Here are the different types of promotions and their abilities below:

    Promotion	Benefit to Unit
    Amphibious	Gives no penalty when attacking across a river
    Accuracy I	+10% City Bombardment Damage
    Accuracy II	Better chance of damaging enemy units
    Accuracy III	Better chance of damaging enemy units
    Barrage I	More collateral damage
    Barrage II	More collateral damage
    Barrage III	+50% Collateral Damage; +10% versus Gunpowder Units
    Commando	Grants speed bonus for units; Use of enemy rails/roads
    Combat I	Grants 10% extra power
    Combat II	Grants 20% extra power
    Combat III	Grants 30% extra power
    Combat IV	Grants 40% Extra power
    Combat V	Grants 50% extra power and healing benefit
    Sentry	+1 Visibility Range
    Mobility	-1 Terrain Movement Cost
    Drill I	One Extra First Strike Chance
    Drill II	+1 Extra First Strike
    Navigation I	+1 Movement Range
    Navigation II	+1 Movement Range
    Guerilla I	+20% Defense on Hills
    Guerilla II	Double Movement on Hills; +30% Defense on Hills
    Medic I	Heals Unit in the same tile; Extra 10% Damage per Turn
    Medic II	Heals Units in adjacent tiles; Extra 10% Damage per Turn
    Flanking I	+10% Withdrawal Chance
    Flanking II	+20% Withdrawal Chance
    Shock	Gives bonus against melee units
    Formation	Gives bonus against cavalry
    Cover	Gives bonus against ranged units
    Woodsman	+20% Jungle Defense; +20% Forest Defense
    City Garrison I	City defense strength +20%
    City Garrison II	City defense strength +40%
    City Garrison III	City defense strength +60%
    City Raider I	+20% City Attack
    City Raider II	+40% City Attack
    City Raider III	+60% City Attack

• Some Units might also have an invisible characteristic. Great People
  (and possibly spies) are an example of this.
• Infantry will have defensive bonuses in difficult terrain, while cavalry will have an advantage attackingranged units such as

  archers.

  Artillery/Siege units are stronger and will allow for damaging all of the units in a stack. Bombardment units are now like

  a hybrid of previous

  games. The damage a unit has is relative to their strength. Again, these changes were done to encourage use of combined

  arms.

• There are no longer separate attack or defense bonuses such as in Civ3. They will have only one basestrength that might or

  might not

  increase or decrease. Units also have advantages or disadvantages against certain units. Pikemen will have a decided

  advantage over mounted units

  and

  Axmen are especially good against melee units.

  • Units strength is represented by the number of units. At full strength, a unit will have three units, and when ittakes damage it loses a

    single unit until it is destroyed.

• Armies have been eliminated (in Civ3 terms, now they will only serve as moving of units together), butmore customization

  and

  countering is available in return as describe above.

• Surrounding and isolating a foreign city with your forces is now
  a new strategy. This puts pressure on the foreign leader and he mighteventually offer it to you via diplomacy. If he or she does not want to trade the city to you, the city itself has a good

  chance to riot because

  the

  city’s population would want to join your Civilization.

• You can
  blockade cities, for example, by moving your naval units close to an enemy city (that means that city can no longerwork its water tiles).

  Water

  resources can also be harvested (this has been known for a long time). If you’re getting all your
  Oil from the water, you are in trouble because another Civ can cut off your oil supply, unless

  you can do something about it and defend your weak points.

• The infamous “Spearman defeats Tank” phenomenon is now gone,
  needless to say.  This has caused a lot of headachesfor Civ fans in the past. This will mean that units that are inferior will not be able to win against more modern

  ones.

• Early on the best city defense unit is no longer the Spearman, it is the Archer. Spearmen are more useful against other Cavalry units.
  Warriors are the weakest unit, however they are perfect for escorting Settlers and/or workers through danger zones (filled

  with wild
  animals as well as Barbarians).

The Multiplayer

Some people, of course, like to play with others online. How the multiplayer mode seems so far is promising.

• This time, Civilization IV will have an integrated multiplayer so you won’t have to wait for expansionpacks like we did

  with the
  Civ3 series. A new co-op feature allows for more satisfying game-play than before when playing with other people,

  as you will form

  alliances against

  the AI, or other opponents. The map generator ensures that everyone starts equally as well, as the map is generated

  randomly. Player in MP will

  also be

  able to form
  permanent or temporary alliances with one or more players. Every game starts
  out with the server host picking rules, players picking factions (and sides
  if applicable) and then entering the game.

• Youll be able to play a very quick online game with a friend orplay long, ruthless campaigns lasting months. In MP, you can start out early, and end up playing well into the modern age,

  something which was

  difficult to achieve with Civ3s MP. In MP, there are five speed
  settings: Blazing, Fast, Normal, Slow, and Snail.

  • Even though, through PitBoss, playerscan play as long as they like, there is a mode which also lets players to play shorter games (100
    turns, from the Stone Age to the Bronze Age for example).
• Right out of the box Civ4 supports up to 18
  players online. This allows basically every Civilization to be played.
• Players are able to compete in traditional turn-based or simultaneous move games either on a network or viathe Internet.
• If and when a player or players are disconnected from the game, a screen (labeled “Democracy”)
  pops-up giving the other players still in the game to vote on what to do. The options are: Kick the player out of the gameand replace his

  Civilization with

  an AI player,
  save the game and continue playing until the player can join back, or just wait for the player to re-connect and proceed

  with the ongoing game.

  Games are

  generally
  easy to save, even if the circumstances are not so bright.

• Team Play: Players can form alliances with each other in multiplayer games. Allied nations will put theiraccomplishments together,

  join forces

  in combat and share all information, even line of sight, benefits of wonders, research (two players, for example, can

  research one thing at the

  same

  time to discover it faster), unit trading, and sharing of territory. These additions deliver a plethora of new strategic

  and tactical options to

  the

  players. Team-Play is available both in MP and SP (Single Player) modes.

  • In Multiplayer, the server browser will include buddy list
    functionality to keep track of friends easier.
  • Timers are set in Multiplayer in order to make everything
    move smoothly (and so people can’t stand there doing nothing for a longer time).
  • Missionaries are very valuable in
    Multiplayer. It’s even possible to force another civilization to adopt your religion, which can potentially bring in a tidysum of money for you.

    Citizens

    can become very unhappy
    should their way of life change so dramatically, however.

• Teams can easily communicate with each other. Example: You are able to put signs
  on tiles and draw lines on the terrain and other players are able to see that and know where to go

  (if a specific location is your goal. This is available in Single-Player mode as
  well). Players can even send little pings to alert teammates of important events happening around their map. Support for

  voice over IP also allows players to talk while playing.

• You can go in and protect your ally’s cities unlike in Civ3.
• There is also a new “Double City Elimination”in Multiplayer which means that if you lose two cities, you lose the game. To go
  into more detail, there are different modes of it. If you take one city it can
  instantly burn to the ground, and therefore you are at an instant advantage.
  You can also set it so the city does not get razed, and if your opponent takes
  back that city, the score is leveled out. The “One City Challenge” option means that you can have only one city. There

  are

  the “Always War” and “Always Peace” options as well. For a game, you can chose one or the other (you are, obviously, unable

  to select both at the

  same time).

  These features can be mixed to create the MP game you want.

• A particularly hardcore game can be createdby playing with teams and handicaps. With two teams (one with one person, set the level to the easiest difficulty so that

  player gets a bonus on

  most all

  areas of game-play) and one with several other people on a normal, or harder difficulty for a greater challenge.

• In addition to the standard internet, Hot Seat, and LAN modes, Civ4
  is playable by email (PBEM), or on a persistent turn-basedserver, or PTBS (named PitBoss).
  • The Pit Boss
    persistent turn-based server will allow for players to play as long as they like and leave when they like withoutdisrupting the game. Players

    can

    also fill in for AI players and join when they like
    (so it is possible to jump in right in the middle of a game and take an AI’s
    role). The server will download the current game state, then a player takes their turn and the server
    afterwards saves for the next player. It is like playing a streamlined version of play by e-mail or hot seat

    multiplayer.

  • The
    Multiplayer pit boss, which will allow persistent multiplayer games of Civ4,
    was released in December.
  • Firaxis will cull all sorts of statistics from multiplayer
    matches, which will let it rank players, which is aimed to avoid some of the frustration when you find yourself in amultiplayer match with

    ruthless Civ

    pros.

• Connectivity: From Jesse “Friedrich
  Psitalon” Fletcher’s MP article
  – GameSpy NAT negotiation allows people behind routers, firewalls, etc, to
  play with no trouble at all – no opening or closing of ports, zones, etc. If
  needed, Direct IP still exists, and WOULD require playing with ports, but the
  only port you need to open is 2056, or whichever port you specify in your INI
  file. No more OOS. Except if you are playing a different version of the game.
  The game has even shown the ability to “resynch” itself if a genuine
  problem arises temporarily (hotjoining players sometimes cause a 1 or 2 second
  OOS).
• Protected copies of all original files will guarantee that everyone in a game
  is playing by the same rules (be it in a casual MP game, orin a
  Tournament).

Customization Flexibility

People do not lie when they tell you some like to customize the game just as much, or even more so than to actually

play it. What’s new

here?

View Section Notes

• Civilization IV will set a new standard for user-modification allowing gamers to create their ownadd-ons using Python and

  XML. It
  is the most customizable version of Civ to date! Basically, full mod support is offered here, and almost nothing

  in the game is

  hard-coded

  (unlike in Civilization III. Firaxis has also said that a fully customizable Government system

  will also be

  available,

  among the many other things…Below are the four modding levels Firaxis games has released information on, ranging from the

  easiest (the Map

  Editor),

  to the most difficult (the Software Developer’s Kit).

• Map Editor: This will probably be like the Civ3 Map Editor. It is the easiest way to mod the game yourway, and yes, anyone

  at all can

  do it

  with ease. Just open the editor and you’ll see the ability for you to tweak and change everything from Cities,

  Technologies, Units, and

  Diplomacy. For cities, you

  are able to add a specific population number (as the screenshot to the left illustrates), culture points, gold amounts and

  even change that

  city’s religion.

  Adding technologies to the ones you already have is also possible. For units, you are able to change the level and

  promotion type of any

  available unit as

  well. Changing the terrain type is also another distinct possibility. Just like you are able to edit Technologies, Cities,

  and Units for your own

  Civilization, you are given the option to change these same aspects for the other available Civilizations in the game just

  as easily. The World

  Builder even

  goes as far as letting you change diplomatic options and relations. The editor also opens the way for cheating. –

  Quoted from CivFanatics’ Hands-On preview. The World Builder can be

  launched at any time during a game so players can add new cities as well as creating new starting conditions. The created

  maps are stored in a

  text-based format, which can

  be opened in a text editor. What this does is basically make it easy for you to edit without even starting the

  game.

• The Flexible XML (eXtensible Markup Language) Files: All values of the data for the aspectsof the game such as

  units, terrain, texts,
  camera controls, graphics scales, mouse and keyboard mapping, links to
  Python, audio scripts, and so forth are stored here. Game

  speed will also be Moddable through the XML files. A perfect example of this is that a player can make

  some units get build

  really

  fast, while making other improvements get built at a slower rate. There are lots of tutorials on the Web for this, so you

  may want to check out

  this

  sections notes and get prepared for it if you are enthusiastic about modding the game (as so many people are). Every art

  asset has a scale value

  is in

  XML, and it can be modified
  the way you like (these include buildings, trees, units, improvements, resources, etc).
  You can also modify terrain-specific movement just by doing a change in the
  XML file(s). An example is “Mountain Infantry”. Also, through XML, players can add new unit or building

  types, change the cost of

  wonders, or add new civilizations. Players can also change the sounds played

  at certain times or edit the play list for your soundtrack. NOTE: You can have custom soundtracks simply by adding music to

  the custom folder.

  You only need

  to edit the XML in order to assign certain pieces to specific eras or remove certain pieces.

• Python: Moving up to a more difficult modding level for most players, Python is a very powerful scriptinglanguage that will allow

  people

  familiar with the scripting language to do things from changing and totally reorganizing the interface (as all of the

  interface is written in

  Python)

  to changing more algorithmic parts of the game like map generation, combat, triggers/events
  (there are, by the way, around 30 triggers including new unit, building, end
  turn, unit move, etc), and even the AI.
  A Python interpreter is also added to the game which makes it possible for
  the player to open it during a game and generate code “on the fly” or check
  other variables. Players will now have the ability to add scripted events to the game like automatically

  generating units when a tile is reached, having specific situations trigger automatic war, or get this, bringing back Civil

  Wars caused by

  unrest, Civ II

  style!

• AI Software Developers Kit (or SDK): For even more advanced modders, Firaxis is offering the entire AI andGame Code of the game.

  Here,

  players

  can change literally everything about the game they want. They can even create and write their own game types to pretty

  much building their own

  game,

  loosely based on Civilization. Literally everything can be changed
  (including the camera position). It has been said that it is very, vary rare for such an amazing modding

  level to be released for a strategy game. The AI SDK will be available shortly after the game ships,
  in early 2006. Modders can do anything short of changing the basic graphics engine, the core Civ engine, or

  the network code.

• Some new modding tools are the: Unit Formation
  Editor (this gives control of where units stand on a tile, how many units are in
  a formation, and under what situations a certain formation is used), Hot-Swapping of Assets (meaning that the computerdetects any changes
  and can load them “on the fly”), Python Scripting for the World Builder,
  Python Interpreter Console, Python Editable UI, L-System (Lindenmayer System) City Building
  (which makes the city graphics look random with each build, but it is also
  used to generate terrain features such as trees),
  Colored Map Overlays… The GameCore DLL is a “Pluggable Module,” which
  will make no assumptions about the underlying platform and hardware,
  [and more].
• The new Bitmap Converter lets you import BMP files and turn those into
  Civ maps, letting you download a topographical map (or a picture of your
  favorite celebrity) and have the game extract sea levels, mountain ranges and
  other information straight from it. Giving the Bitmap Converter any BMP image
  and it will make a Civilization IV map from it. Everything blue becomes water, everything green becomes grass – withthe proper image even

  entire mountain formations can be achieved
  (fives images: Terrain type, plot type (mountain, hills, flat, water), rivers,
  features (jungle, forest) and resources..
  This tool is already available. Click here to download it (it

  did not ship with
  the game).

• A debugging mode is included, so you can switch off the FoW (otherwise known as the “Fog of War”) and watch how theAI behaves and

  plays.

• A number of pre-built scenarios will also be available with the
  game as it ships that also have different victory conditions. The World War II scenario, for example, will start you withall your cities and

  military units

  already built,
  and instead of conquering the whole world, you may have a more focused goal, such as taking or defending Paris.
  There will also be a World-Map included. An American Revolution scenario will be included in the game as well. Here is a

  screenshot of it.
  Greek World, Earth 1000 AD and Desert War are also some scenarios which have
  been included in the game.

  • Even more Scenarios and a really top-notch tutorial (to help new players out) will also be included in
    Civ4. There is also no doubt thatwith the presented modding abilities, we will see some very exciting creations from all corners of the Civ

    community!
