This game is pretty old, and the graphics are terrible. But I downloaded it because it supports the clutch for my G25.
Now the training exercises are pretty kool, but the racing itself is far from realistic.
First of all, the AI aponents love to bump you off the track, and that is not realistic.
Second of all, your car skids and loses traction when going 20-30km/h.
that is NOT realistic. This game has obsolete game physics. The only thing I can find that's realistic is the gear shifting, but you can't tear your clutch. So once again, not realistic.
I hope GTR 2 will seem more realistic, a good thing this game is torrent'ed because it's not worth buying.
I find GRiD to be 100x more realistic than this game.
