Do not buy this game!
Now, on to the tracks: the game has 30 tracks, across the USA and the world including San Francisco, New York, Cape Kennedy, Easter Island and Niagra Falls. It sounds like enough variety to make you keep playing for a while, but believe me, it isn't. There just isnt anything in the tracks that makes you want to go back to them, once you've been through it once, you have pretty much seen it all.
The graphics in the game are decent, not too flashy but they get the job done and the music is not good at all. the sound effects are OK, with nice engine roar and tyre squeal. The game modes are OutRun, Heart attack and time trial, so nothing that is totally new. So, in hindsight, I wish that I had bought Burnout instead, I played on it at a friend's house and it was much, much better.
So if you have a thirst for a racing game, stay away from this rubbish.
