Video game development is rarely about one man, but if it was, then Terence Groening should certainly get a mention for his contributions to the genre as the man responsible for the physics of Sportscar GT, EA’s PC F1 and NASCAR games of the early 2000’s, rFactor, rFactor 2 and every title and rFpro simulator that spawned from ISI’s engine.
This interview with RSC details his early life and career, through to him joining iRacing in 2021.
RSC contains a database of 153 developers, 467 software titles, 374 cars, 42 bikes, 242 tracks and more...Originally working in military simulator design, this Michigan-based studio developed Zone Raiders for Virgin Interactive before moving to Electronic Arts for publishing their second PC title, Sports Car GT, when Westwood Studios (their SCGT development partner) was acquired by the software giant.
Known primarily for their mod-friendly SCGT and rFactor racing platforms, ISI also developed Formula One and NASCAR titles on PC for Electronic Arts, but perhaps their lasting contribution to the genre was the licensing of the isiMotor engine that allowed studios such as 2Pez, Blimey! Games, KW Studios, Motorsport Games, Reiza Studios, SIMBIN Studios, Slightly Mad Studios, The Sim Factory, Tiburon and rFactor 2‘s ongoing developer Studio 397 to begin with or release on an evolution of their software.
Another fork of the isiMotor engine, rFpro, continues to be developed and is used by a wide array of automotive companies for both road and motorsport simulation.
