Page "Sim racing" Paragraph 29

In August 2005, ISI released rFactor, a highly modifiable sim based on their gMotor2 physics engine.

Notable for its initial download-only distribution model, rFactor originally released with fictional cars and tracks.

ISI's encouragement of the enthusiast mod community has led to an unprecedented number of add-ons, including 800-horsepower-stock cars.

Subsequent releases of rFactor featured Formula One cars and recreations of real track layouts under fictitious names.
