Since there are several ways to win (military, diplomatic, or cultural), it is up to each player to determine how best to manage the division of labor. As game time progresses from ancient times through the modern era, a civilization will acquire new technologies, which in turn enable interesting new abilities and enhanced power. Like in the previous titles in the series, the point of the game is to expand the influence of a civilization through resource management, conquest, or trade with other civilizations. Each civilization has its own particular strengths and weaknesses - some are more scientific, for example, while others have stronger cultural or military attributes also, each civilization has its own unique unit, and is more prone to certain forms of government while shunning some others.
Players control one of 15 historic civilizations (Aztecs, Egyptians, Russians, etc). Sid Meier's Civilization III is a turn-based strategy game where the objective is to rule the planet with the civilization of the player's choice.
