Sid Meier's Colonization is a computer game by Brian Reynolds and Sid Meier released by MicroProse in 1994. Colonization is much like a more developed version of Sid Meier's previous game Civilization (1991) in visual design and handling, but the two have marked differences in gameplay. Instead of forging a nation from nothing, the player manages the cross-Atlantic expansion of an established one in the service of the Crown. As the colonies become more self-sufficient their subservience shifts from boon towards bane, and to win the player must ultimately declare independence and defeat the Royal Expeditionary Force in battle.
