I think they could've made a better job on this game. Ok it has some new good things such as the 3-D implementation which alows loops and the variety of cars is something really awesome.
But the fact that there a choice between Max Speed and Acceleratio should not be up to the user, it should be dependant on the car as everything else. Due to the high speed it's really hard to control the car on curves a type of airbrake should have been implemented in order to help this. The difficulty isn't that much of a challenge, only the hardest bits. The music is somewhat cool but it could've been better. And finally graphics are good, but the pop-up is just too obvoius and it couls've been disguised a bit more.
