About the base game:

Originally created by legendary game designer Sid Meier, Civilization is a turn-based strategy game in which you attempt to build an empire to stand the test of time. Become Ruler of the World by establishing and leading a civilization from the Stone Age to the Information Age. Wage war, conduct diplomacy, advance your culture, and go head-to-head with historys greatest leaders as you attempt to build the greatest civilization the world has ever known.

Civilization VI offers new ways to engage with your world: cities now physically expand across the map, active research in technology and culture unlocks new potential, and competing leaders will pursue their own agendas based on their historical traits as you race for one of five ways to achieve victory in the game.
