Moose I figure you are asleep now, but I will check in tomorrow.
It's a pretty cool game, just as I remember from XBox.
Physics are a little arcadey, but not very much. You can still lock the brakes and get oversteer and understeer and you can get sideways and steer with the throttle.
Very stable, no crashes yet. Just some minor graphics glitching from time to time.
My biggest gripes would be:
1. Force Feedback support sucks. Just some vibratey stuff. No steer forces. Rally Trophy blows it away in this area.
2. Engine sounds are pretty weak.
Otherwise, I really dig it.
