Sid Meier's Alpha Centauri

Sid Meier's Alpha Centauri is a 4X video game, considered a spiritual sequel to the Civilization series. Set in a science fiction depiction of the 22nd century, the game begins as seven competing ideological factions land on the planet Chiron ("Planet") in the Alpha Centauri star system. As the game progresses, Planet's growing sentience becomes a formidable obstacle to the human colonists. Sid Meier, designer of Civilization, and Brian Reynolds, designer of Civilization II, developed Alpha Centauri after they left MicroProse to join with Jeff Briggs in creating a new video game developer: Firaxis Games. Electronic Arts released both Alpha Centauri and its expansion, Sid Meier's Alien Crossfire, in 1999. The following year, Aspyr Media ported both titles to Classic Mac OS while Loki Software ported them to Linux. Alpha Centauri features improvements on Civilization II's game engine, including simultaneous multiplay, social engineering, climate, customizable units, alien native life, additional diplomatic and spy options, additional ways to win, and greater mod-ability. Alien Crossfire introduces five new human and two non-human factions, as well as additional technologies, facilities, secret projects, native life, unit abilities, and a victory condition. The game received wide critical acclaim, being compared favorably to Civilization II. Critics praised its science fiction storyline (comparing the plot to works by Stanley Kubrick, Frank Herbert, Arthur C. Clarke, and Isaac Asimov), the in-game writing, the voice acting, the user-created custom units, and the depth of the technology tree. Alpha Centauri also won several awards for best game of the year and best strategy game of the year.
