The mechs in I.G.P.X. Immortal Grand Prix Racing look nice, with a definite anime feel to them, but all in-game graphics are 3D with the exception of the clips from the show. You can change the color of the mechs on your team, but only by choosing one color per mech; the color you choose is representative of a color scheme, rather than the only color that is used on the mech. Gamers who are looking to simply change the look of their mechs a bit may be fine with this, but tweakers will be annoyed.
Sound effects sound good and have an anime feel to them. One nice touch are the short audio clips of your coach praising or admonishing you at the end of each race. I get the feeling this character is the coach of the starring team in the I.G.P.X. Immortal Grand Prix Racing cartoon series.
The music pumps pretty decently with primarily techno music, with a touch of rock flair in places. This provides a nice aureal backdrop for the action at hand, although I won't be looking for it on CD to listen when I'm not playing the game.
The camera in-game is very interesting. It is a 3rd person view, but the camera is not always pointing the direction you're facing or forward (regardless of whether these are the same). This gives the game a more cinematic (or, at least, television show) feel; the camera angle is usually the best angle to show the action. The insane thing is -- the camera works for I.G.P.X. Immortal Grand Prix Racing. Since you're not concentrating on just racing around the track, the camera allows you to see what's going on around you and let's you concentrate on kickin' can.
