"Sid Meier's Civilization IV: Colonization is a remake (a total conversion using Sid Meier's Civilization IV engine) of the 1994 game Sid Meier's Colonization. Players control settlers from one of four European nations, Spain, England, France, or the Netherlands, that are trying to conquer/colonize the New World in the time period between 1492-1792. The final goal of each player is to build up their colonies and a standing army, then declare independence from their mother country and defeat the military force that the King sends to crush the rebellion."
