Picked this up a few months ago after years of searching, and it's nowhere near the train wreck I heard it would be. Been giving it a fair belting and I reckon it's a pretty damn good game. On to my list then:

1. Soundtrack. IMHO best W'O soundtrack there is.
2. Atmosphere
3. Long tracks. Feel like going for an afternoon drive at 1000+ kph?
4. Graphics. Nice to see a Wipeout game on the PS2
5. Upgrading ships. The four versions of each ship are ace.
6. There's a track that runs around and through Ayres Rock!? Hell yeah!
7. Beating pilots on a specific course before you unlock their ship.
8. Extra details on ships (Airbrakes, some have what looks like a rudder)
9. More than 8 ships per race. Makes for more competition.
10. Mandrashee. Just...damn.
