isiMotor1

"The prehistory of isiMotor2 begins with a string of games built on the isiMotor1 game engine developed by Image Space Incorporated (ISI) in the late 1990s and early 2000s: Sports Car GT (released 1999), Hot Rod Monster Squad, F1 2000, F1 Championship Season 2000, F1 2001, F1 2002, F1 Challenge '99-'02, NASCAR Thunder 2003 and NASCAR Thunder 2004." -isiMotor2 Community AI Documentation

isiMotor2

"After years of independent development by ISI, a new game engine, isiMotor2, was ready for use and was licensed to SimBin Studios for their upcoming title FIA GT Racing Game: GTR. SimBin had come into being by creating and releasing a free, unlicensed FIA GT mod for F1 Challenge – for more info, see this YouTube video by GPLaps. They were now developing a licensed game of their own after purchasing a license for the right to use isiMotor2 from ISI. This was the first of many sim racing titles built on isiMotor2. Over time, a number of different developers would license isiMotor2 for use in their games." -isiMotor2 Community AI Documentation
