With Civ being a long standing series, it is at the end not surprising that some civ fans grow up being developers, who take some inspiration from Civ for their own games. Examples of such games are ZOR or Elaborate Lands, and now another civ-fanatic has come forward to present his own game: The Settlements. This game is in a very early stage, and will at the end consist out of a turn-based world mode, and a real time city building mode, a bit similar to Total War. If you want to have an early peek at the game, then check the thread by the developer here.
