Epic Games
Epic Games, Inc. is an American video game and software developer and publisher based in Cary, North Carolina. The company was founded by Tim Sweeney as Potomac Computer Systems in 1991, originally located in his parents' house in Potomac, Maryland. Following his first commercial video game release, ZZT, the company became Epic MegaGames, Inc. in early 1992 and brought on Mark Rein, who has been its vice president since. Moving their headquarters to Cary in 1999, the studio's name was simplified to Epic Games. Epic Games develops Unreal Engine, a commercially available game engine which also powers their internally developed video games, such as Fortnite and the Unreal, Gears of War and Infinity Blade series. In 2014, Unreal Engine was named the "most successful videogame engine" by Guinness World Records.
