My opinion:
Game coding - 3,5/5 (improve the handling, it's so tough even with quality zero and traction control off!)
Game art - 4,5/5 (make a burst of fire come off when a car is using nitro)
Game sound - 3,5/5 (add some more music, make it possible to change music during race, and synchronize those engine sounds!)
Player impressions - 3/5 (add more tracks, make cars customizable and add a campaign mode)
Overall - 3,5/5 (good game, needs improvement)
