Firaxis has published the next “Challenge Of The Month” for Civ6, and you actually get four challenges: You can play this game as Joao III or as Matthias Corvinus, on Prince or Emperor level. You start on a large map in the Renaissance era, with marathon speed and a 200 turns limit. The resources are abundant, but not on your continent, but only in the new world. You have until July 16 to conquer this new world! For more information please check this thread.
