Firaxis Games is a computer game developer. It was founded in 1996 by Sid Meier, Jeff Briggs, and Brian Reynolds upon leaving Microprose. The company focuses on strategy games and is based in Sparks, Maryland in the United States. Firaxis has produced several games, including Gettysburg and Antietam, based on their namesake famous American Civil War battles, and Sid Meier's Alpha Centauri, a space colonization game taking place in the Alpha Centauri star system. In early 2000, co-founder Brian Reynolds parted with Firaxis to form his new studio, Big Huge Games. Firaxis Games then went on to release Sid Meier's SimGolf, a golf course building/management game. Perhaps their most popular releases have been Civilization III, and later Civilization IV, sequels to Meier's original Civilization game.
