This is a pretty cool game but it's a bit too difficult for me, which is rare when it comes to racing games. It requires absolute perfection to get anything above a one star rating on the tracks. That brings me to another issue I have; it's not really a racing game. It's nothing but time trials and you never race against any opponents (though there is traffic). Instead it's against a checkpoint timer and stars that show you how close you are to meeting the time goals of the track you're on. I would much rather be racing against AI opponents than a clock, and it seems the goals you're racing against don't have to deal with the traffic like you do. If it had to deal with the traffic I imagine it would feel more fair and I might actually be a bit better at it. lol
All that said it looks great and it's fun to play. At the price I still recommend it simply for the fun of driving. The track generator is also a cool feature, and the first time you drive on a created track you can just enjoy the trip without having to worry about a timer or rating. I would give it a 7/10.
