Pluses: New tracks, Career Mode, Great Soundtrack and Extreme Racing.
Minuses: Out of control Wall bouncing, Speed up ramps (ala Wipeout - the XG3 Boost system worked better), limited opponents and the main problem - its just too easy.
If you have mastered previous titles you may find yourself, like me beating the whole game at the first sitting.
Nevertheless, a great addition to your collection and a must for series fans. Extreme speed, Extreme fun. Go get it.
