TeamVVV's youtube videos make it look pretty awful. He brakes too late or too early, missing turn in points and apexes by miles, can't change gear at the right time... Yet the car magically gets round the corners.... and overtakes.... In his Suzuka one he compains about Kubica's AI driving, claiming he's (it's) weaving all over the place - whilst he weaves all over the place himself!!!
The graphics and the wet weather might redeem it, but it looks pretty crap to me in terms of driving. And I'd much rather have physics over eye-candy and features.
Think it might have to be torrented first to see if it's worth giving money for. And that's not something I do lightly!
