Released in August 2005, it competed with games like NASCAR Racing 2003 Season, Live for Speed, and GTR.** The game featured many technical advances in tire modeling, complex aerodynamics and a 15 degrees of freedom physics engine. It also featured multiplayer.**
rFactor was developed by Image Space Incorporated (ISI), which has been developing simulators since the early 1990s for both commercial and military purposes. The isiMotor2 on which the game is based is a direct successor to the engine used in previous titles developed by ISI, most notably F1 Challenge '99–'02, released through EA Sports. The isiMotor2 engine was also used in many other simulation games, and in rFpro. The game was made without ISI's longtime publishing partner at the time of EA Sports, and featured exclusively custom tracks rather than licensing real ones.**
Development
In an early review of an rFactor preview, published on AutoSimSport, Jon Denton said: "What the tire model in rFactor does very well is that it models the relationship between slip angle, self aligning torque and cornering force - and it does this better than anything that has come before".
Writing on HonestGamers, Paul Josua concluded: "It's a little unfair to hold ''rFactor'''s lack of accessibility against it as it has clearly set out to be a simulation racer. It does a fine job of that, but those who don't demand flawless simulation are better served looking elsewhere".
rFactor was a finalist for *PC Gamer US'''s "Best Racing Game 2005" award, which ultimately went to GTR: FIA GT Racing.
Sequel
ISI developed rFactor 2, which includes weather effects, reflections and accurate shadows on a variety of textures. It was released on March 28, 2013.
