What's the Best Simulation Racing Game?

I'm new to 360 and I wanna get the Gran Turismo of Xbox 360.. What would that be?

Forza 3 is the only sim I can think of.

Go to the Recommendation Thread they will help you there.

The best racing game I've ever played on the 360 is Forza Motorsport 3.

Grand Turismo is low in creativity, i'd say. Forza Motorsport 3 is one of the best.

Like everyone else has said, get Forza 3.

Yaris...its on XBLAAnti-Venom

There is no real simulation racing game on the xbox 360.
But ye what everybody said Forza 3 is actually the only one who came close to it.

Did someone already mention Forza 3?
