I have been playing Epic Mickey for a couple of days, and I will say it is the best game I have played in while.
It reminds me of a mix between Banjo Kazooie and Gex Enter The Gecko, with a touch of Super Mario Sunshine.
The game is clever, and exciting. I really like it, and recommend it to all wii users. If you don't have a wii, find a friend that has one and play this game.
If you liked the N64 years, you will really like this game, because it has the feel of one.
