When they are controlled by AI, each leader also pursues a specific agenda throughout the game, which modifies the AI behavior of this civilization. Each civilization in Civilization VI has a unique ability and two other unique components: a unit and a piece of infrastructure, which may be a building, a district, or a tile improvement.Ĭivilization VI makes a distinction between a civilization and its leader, not unlike Civilization IV - each civilization can now have multiple leaders, and each leader comes with their own unique ability, which is added to the other unique traits of the civilization (and, in some cases, provides an additional unique unit, piece of infrastructure, and/or Governor that further augments that civ's and leader's specifics). Civilizations are playable factions, each of which represents a historical nation, empire or cultural group.
