The models of the ships are detailed and the special effects are top notch. I was pleased to find that, for the most part, collision detection was excellent as well. The first occasion that I saw a clipping issue was when I took a wrong turn at ridiculously high speeds and ran straight into a wall. If it were reality instead of a game, I still probably would have seen the inside of the wall.
There's even two "skins" you can use for the game's UI itself. The default skin is a bright skin with a lot of white, while the "Hacker" skin is a dark skin with a black background. Not only is it wicked cool looking, it just might save battery a bit when you're in the menu screens. At any rate, it's a nice feature to throw into a game.
As for the sound, the sound effects are excellent, and the soundtrack has 19 different techno / industrial tracks from artists such as Aphex Twin, Tiesto, Thenroc, Tayo Meets Acid Rockers Uptown, Stanton Warriors, T Power, Rennie Pilgren & Roxiller, Plumb DJs, Photek, Paul Hartnoll, Ming + FS, LFO, Jay Tripwire, Friendly, Freq Nasty, Elite Force, Drumattic Twins, Cosmos, and Cold Storage. Any of these are excellent for accompanying your fight to be the first to make it across the finish line alive.
It's hard to wrap one's head around the fact that a game can look so good on a portable system. If you get a PSP and can even remotely stand the Wipeout series, you owe it to yourself to get Wipeout Pure - if nothing else just to be able to show up your non-PSP wielding friends.
