Edge Games was founded in California in 1990 by Tim Langdell. At that time, it acquired the intellectual property assets of Langdell's former company, Softek Software, itself founded in 1980 in London, England. Softek's catalog includes several well known games, including: Fairlight, released in 1985, and Garfield: Big Fat Hairy Deal, released in 1987.
Until the availability of "Racers" for the PC in 2010, Edge Games had not released a new title since 1994, though the Edge website states that two other multi-platform titles: "Mirrors", and "Mythora 2" are "coming soon", as are the PS3 and other platform versions of "Racers". The website also states that they are porting some of their Commodore 64 games to WiiWare.
