As a direct ancestor of iRacing, the ‘Grand Prix Legends engine’ had multiple stock car racing false starts, before eventually releasing as NASCAR Racing 4. The original NASCAR 3, cancelled and replaced by one that used NASCAR 2’s engine, is barely remembered.
Originally known as Papyrus Design, the legendary Massachusetts-based software studio developed highly-regarded simulation titles and published with Electronic Arts, Virgin Interactive and Sierra before their shutdown by Vivendi, owners of Sierra, in 2004.
Co-founded by arguably the father of the modern racing simulation, David Kaemmer, the studio created NASCAR and IndyCar titles that consistently pushed the genre forwards.
Their groundbreaking Grand Prix Legends game engine was used in three NASCAR titles between 2001-2003, evolving to become iRacing after Kaemmer re-acquired former Papyrus assets for his new company.
