I got a copy(ahem) of this and i wasn't too impressed with it. It has better graphics than the first Rollcage but the tracks are lame, there was one track that was really cool and that's about it. Pretty much a letdown for you Rollcage fans out there.
Same here, i've completed every racing class except the last one in two sittings. I'm going to beat the last class today, lol. It's one of those games that's really good if you want to just veg in front of the PC and play something with alot of eye candy that is easy to learn and moves fast.
