The guys at hotgames.com rated it as one of the top driving games for PC this year. It has averaged a review rating of 8.3 out of 10 overall according to gamespy( polling a couple 100 sites). I think it is cool just because it is all brand name parts and vehicles so I can build up my truck just like it is in reality.
All that being said here is a link where you can get it new off e-bay for way less than in the store.
