This was the first public simulator release from military simulation developer Image Space Incorporated, and was initially funded by Virgin Interactive with publishing assistance from Command & Conquer developer Westwood Studios. Prior to release Electronic Arts acquired both Virgin and Westwood, along with Sportscar GT.
Delays in release caused by the transition to EA gave ISI additional time to work on the product, which led to a number of unplanned features being implemented in the software. The delay also led to the open nature of the .ini files that gave an opportunity not only for last minute developer tweaking, but also for the sim racing community to create a wide array of mods upon release.
