Sounds like an interesting concept, freedom in choice and ways to do things is something I like in games.
I have a few problems with this game though...
1.I don't own a wii
2. I don't like Mickey Mouse
With Mickey as main character I am a bit worried about the plot, whether it will not be too easy, childish, simple, Disney-like. Which it will be anyway, given that, no matter what path you choose, you always end up winning.
Maybe I don't like the concept that much anyway...
