: Introduces Great Ages (Golden and Dark), City Loyalty, and Governors.

The signature innovation of Civilization VI remains its "unstacked" cities. Unlike previous entries where districts were mere buildings within a city tile, VI forces players to physically place Campuses, Holy Sites, and Industrial Zones on the world map. Version 1.0.12.68 perfects this system with adjacency bonuses that require genuine strategic foresight. A dam placed in a floodplain, flanked by an aqueduct and an industrial zone, yields exponential production. The Gathering Storm expansion further complicates this by introducing environmental effects: volcanoes fertilize but destroy, rising sea levels claim low-lying districts, and power plants generate CO2 that accelerates climate change. This creates a compelling late-game tension between short-term industrial gain and long-term ecological survival.
