I wasn't too impressed with RacePro. I didn't think the physics were that great, either. Better than Forza's in a lot of respects, sure, and the track surfaces are mostly well done(dont expect glass smooth asphalt like in Forza!), but its not quite up-to-par with the PC sims it was supposedly based on. Track selection is good if you get the DLC, but there's not a ton of tracks without, although whats there is very good. Online is decent fun. I enjoyed having indefinite practice sessions where you could go to the pits and mess with your setup during the session with everybody else around, then do qualifying and then the race. The collision system is crap, though, which can be very annoying. There were lag problems when I played(might have been patched?) as well. But really, I think it was the 30fps that killed me the most. The graphics were already pretty bad and at 30fps, it was actually affecting my driving.
