Worse than the first one.
Average graphics, there's nothing special here, bad damage system*, and the cars sound pretty much the same. The gamplay isn't fun, that's all I have to say about that.
I'm begining to think that Sega is loosing whatever talent they had; the latest Sonic games were absolutely horrible, the only decent original games that they have put out in 5 years are the Condemmed games. Fin.
Completely off topic: The original Sonic games were great arcade titles; I really had a lot of fun with them. The latests ones (I know they are aimed at kids) they were terrible, they need to let Sonic die.
