Summary
Torture
The Good
(silence)
The Bad
Horrible graphics, especially in the cars, no AI, opponents impossible to beat, traffic seems to be planned as evil as possible, cops are also impossible because they approach you and pass you, so you have to slow to zero and start again. That process takes WAY too long. Also, your car seems like is is just DYING to act stupid, i.e. spinning, going too slow, or refusing to steer out of a cars way, resulting in a collision. Did I tell you about crashes? One crash takes over 10 seconds for you, but an opponent crashing in worse circumstances is on the road and passing you in 5 seconds. Oh, and the game's pretty much impossible. I'll shut up now.
The Bottom Line
If you want an arcade racer, buy NFS:II or later version. TD4 is more like being tortured by monkeys.
