Longevity & Community: Despite being technically replaced by newer titles, the community-driven Content Manager and Custom Shaders Patch have effectively "remastered" the game, adding modern features like rain, day/night cycles, and advanced physics.

Modding Scene: It is arguably the best-supported racing sim in history. From the Shutoko Revival Project for street racing to high-fidelity GT3 cars, the variety is unmatched. Do not reinstall the game
