The collection
Each classic fully documented — and one click away from playing online in the browser emulator.

The original. Guide a civilization from 4000 BC to the space age — found cities, research advances, and outlast rival empires on a world of your making.

The Windows port of the original — identical rules and rivals, with a mouse-driven interface, richer palette and the desktop convenience of early-90s Windows.

Cross the Atlantic for a New World of trade and rebellion. Build colonies, master the goods economy, recruit Founding Fathers — then declare independence and defend it.

The celebrated sequel — an isometric world, your High Council in full-motion video, firepower and hitpoints, and twenty-one civilizations across six levels of difficulty up to Deity.

The first official scenario pack: twenty historical and speculative campaigns for Civ II, including eight player-made 'Best of the Net' scenarios — an early salute to the modding scene.

Civ II goes sci-fi and fantasy: colonize Mars, fight through Midgard, chase Jules Verne — plus the powerful editors that turned players into scenario designers.

The complete Civ II: base game plus Conflicts in Civilization and Fantastic Worlds, with LAN, modem, hotseat and internet multiplayer. For many, simply 'the' Civ II.

The engine's final evolution — multi-map worlds, animated units, and fantasy and sci-fi campaigns that pushed Fantastic Worlds' ideas to their limit.
