There have been no direct sequels beyond "Alien Crossfire", something that writer Greg Tito attributed to Reynolds leaving Firaxis in 2000 to form Big Huge Games. "Alien Crossfire" producer and lead designer Timothy Train also left Firaxis with Reynolds. However, a spiritual sequel, "", was announced by Firaxis in April 2014 and released on October 24, 2014; several of those that worked on "Alpha Centauri" helped to develop the new title. A review in "Polygon" noted however that while the new game has better graphics, its story fails to rival the original, a sentiment echoed by another review in the PC Gamer. Another in Endgadget noted "as a spiritual successor to "Sid Meier's Alpha Centauri", however, it's a cut-rate disappointment".
