Firaxis announced that Civilization VII will introduce a feature allowing players to engage with a single civilization throughout an entire campaign. The upcoming Test of Time update, launching on May 19, will be a comprehensive, free overhaul based on player feedback. Key features include the introduction of "time-tested Civs," allowing players to maintain their civilization across ages, a revamped victory system with dynamic conditions, optional side objectives for various playstyles, updated map generation techniques, user interface improvements, balance changes, and a complimentary leader for all players.
