It's a very fun game when you're in a race and have the option to use weapons, turbo etc. but time trials are kind of boring. Also the game can be annoying at times, like when you crash in to sunday drivers because they appear from nowhere and give you very little time to swerve around.
My brother has it. He says it's an enjoyable game but frustrating as normal drivers tend to appear out of nowhere and oppponents can magically catch up with you even if they crash and you get miles ahead.
