I have been playing this game for a few days now. Its good fun, 2 player races can keep you entertained for hours. I agree that the graphics are no way as good as something Like MotorStorm, in fact i haven't seen a game yet that lives upto Motorstorm!
The driving style is totally arcade style, long powerslides and no real sense of control over the car but somehow you manage to get round the corners normally by the computer seemingly helping.
Its a good arcade style driving game, not aimed at realism.
If you want fun fast and easy - get this
If you want incredible graphics and endless realism(almost) and gameplay - get MotorStorm
