Firaxis Games, Inc.

Firaxis was formed in 1996 by the three legendary game creators Sid Meier, Brian Reynolds and Jeff Briggs. Before forming Firaxis, these three created classic hits like Railroad Tycoon and the Civilization series at MicroProse Software.

The company largely focuses on Sid Meier games, first with Sid Meier's Gettysburg!, Sid Meier's Alpha Centauri, and later Sid Meier's Pirates! (2004), and the continuation of the main Civilization series with Sid Meier's Civilization III and beyond.

In 2005, the company was acquired by Take-Two Interactive, joining the 2K Games publishing label. In March 2006, due to cost-saving measures, fellow Take-Two development studios PopTop Software Inc. and Frog City Software were merged into the company.

In the 2010s, the company would revive the X-COM series and it would become its second flagship franchise alongside Civilization.
