They really ruined that game with those idiotic Werehog thing.
I had tons of fun with the speed levels, great visuals though I played the Wii version, nice level design, good pathways... and then came the werehog.
I stopped playing the game because of Werehog levels.
Also, the PS3 version may look better but it has one great disadvantage to the Wii version:
Loading screens. Especially in the city there is a f"ckload of loading screens, it really pisses you off.
The Wii verion conveniently solved all those unneccecary screens with a town map making the unneccecary story and information search much faster.
It may not look that nice but comparing the incredible difference in loading- and searching times (for people who want to talk to you) ,that's more than worth it.
Unfortunatly I've nerver seen the X-Box version so I can't really say anything to that one.
