To build their cities, players must balance negotiations with several groups: the natives of the Americas, colonists from the player's home country and other colonists from the old world. Sid Meier's Civilization IV: Colonization does not require the original Sid Meier's Civilization IV in order to play. A Mac OS X version was released in December 2009. The Windows version was released on September 21, 2008. The victorious player is the first to build up his colonies and army, declare independence from the mother country, and defeat the military force that the king inevitably sends to crush the rebellion. Players control settlers from one of four European nations, Spain, England, France, and the Netherlands, that are trying to conquer/colonize the New World in the period between 1492–1792.
Sid Meier's Civilization IV: Colonization is a remake (a total conversion using Civilization IV engine) of the 1994 turn-based strategy game Sid Meier's Colonization.
