Pros AMAZING graphics and realism, Custom soundtracks (YAY!!), Very well thought out tracks, very user friendly controls and a perfect learning curve.
Cons The storyline basically SUCKS!
Summary The good: This is a one-off futuristic racer exclusive to Xbox, the tracks are well thought through and have plenty of surprises to keep you on your toes. The custom soundtrack support is an absolute GODSEND! The controls are good and the only challenge for graphics and realism to this game is Halo 2.
The bad: The storyline is very bad, I would describe it as "Crap-tacular" (Spectacularly crappy).
Why should you buy it?: One word: Multiplayer
