I wont play a driving game which does not have Good motion support. Motorstorm feels so much better and is what i am used to from my own car.(my car has a steering wheel NOT a thumbstick)
GT5p is rubbish using thumbsticks it would feel more like you are driving a remote control toy.
So unless GT5 had GOOD motion steering like Motorstorm i wont even bother with it. And will happily wait for Motorstorm 2 which is a better game instead.
