There may be some new content, but it's essentially going to be the same game. I'd be surprised if there is anything new though, but that's just my hunch. --- "A man who lived in dreams. That's who he was."
Same game with 3D and far superior controls. If you don't mind the Wii version's controls and have no interest in 3D or portability, just skip it. --- NEVER judge a game you have not played. -Granville
