From Strategyinformer.com: "To make clear what Civilization: Beyond Earth truly is to the average gamer familiar with the series and its history, I need to explain something quickly - 2K, and thus Firaxis, the Civilization development team, can't legally make a game called 'Alpha Centauri.' That name sits with EA.
For all intents and purposes Sid Meier's Civilization: Beyond Earth is a spiritual successor to Sid Meier's Alpha Centauri, the 1999 space-faring classic so frequently referenced in Civilization titles since. The Civilization name doesn't just bring with it brand recognition, though - it also adds interesting wrinkles to the game, with some systems from the generally well-received Civilization V making it out of orbit and to brave new worlds.".
