Fantastic sequel...lots of fun.
It takes a while to get used to the speed that everything happens and can be very frustrating during the first couple of hours of play, but once you "catch up" it is a blast battling the other cars while trying to maintain a good line through curves.
I'm not a big fan of the new weapons, but the new tracks are really cool. Being able to take steep dives, loops and go upside down adds an exciting new twist to races. Sometimes the track is clear and you can see through to the city below which is also pretty cool.
If you are a fan of racing games (like me) I highly recommend this game...
