It is such a shame that there is just as much wrong with this game than there is right. It has great realistic graphics, decent sound, and realistic (for the DS) gameplay. The handling of some of the vehicles is great. Designing your own tracks is also good fun, as is multiplayer. However, there are two BIG problems with the single-player game- Firslty, your opponent cars (and there are a lot of them) don't have any hesitation banging into your car if it is in the way of their racing line. In this respect, the AI is rubbish and unfair- sometimes you feel like the whole pack have teamed up against you. Secondly, and this is the biggy, the other cars do NOT take damage, unlike yours!!! Yes, not only do they take pleasure in banging into your car, but they never get penalised for it. Too many bumps, and it's into the pits for you to carry out repairs. And not ONCE do you ever see a computer controlled car going into the pits, simply because they never have to. This really knocks the score down for me, and makes the game frustrating, especially when the control is so good.
