if amazing phyx includes looking retarded while backfliping on a bike, then sir, you got an incredible game. Other than that, driving a car look like you got oil in those streets + you dont have any tires + the fact that if you crash on a NRG-900 you wont fall (according to the speed obviously) and when you're on a freeway or w/e that bike's name is, you fall even if you break too much.
The only good thing in this game IMO are those graphics.
@ontopic: Storm, why dont you download it, test, and if you like you buy it? Much easier tbh
