About Galactic Civilizations® IV

Galactic Civilizations IV invites you to explore the galaxy, research new technologies, meet alien civilizations and build an interstellar empire designed to endure the test of time. As the leader of a fledgling space-faring species, you guide your people to settle new worlds, construct new kinds of starships and fight wars to ensure survival in a frequently hostile universe. This strategy and simulation title fuses 4X gameplay with grand strategy on PC.

Exploration, expansion, exploitation and extermination are only the beginning. An in-game storyteller works alongside a sophisticated AI strategist to keep the living, lore-rich universe populated with opponents who pursue their own agendas and possess the intellect to act on them. The Core World and Colony split system lets you play tall by linking many colonies into a handful of resource-boosting core worlds, or play wide by manually improving numerous lower-class planets for a sprawling empire.

Creativity is a defining feature, powered by AlienGPT, which lets you describe your civilization's characteristics, preferences and aspirations and watch the game weave them into distinctive lore, diplomatic dialogue, starship selections and ambassador portraits. Combined with tools to craft custom fleets, this gives you unusual freedom to shape your own cosmic legacy. For strategy enthusiasts, it delivers a deep, adaptable galaxy where your choices define how history unfolds.
