[quote name='eau']Is there a definitive version to get out of all the systems that it is available on?[/QUOTE]
From what I have read, the 360 is the "best" as it's the best graphically, but it sounds as if all platforms have issues and none are leaps and bounds better than any other one. It's basically get it for the system you prefer.
So I ordered the Wii version online to save some gas from making a TrU run when I don't even know if they'll have copies (and calling the TrUs near me is a crap-shoot for reliable info).
