If you managed to snag a Wii U on Sunday, and if you've managed to keep your console from bricking so far, then Disney Epic Mickey 2: The Power of Two is probably one of the better launch titles for your new console. Of course, it's also available on the PS3 and 360, with a side-scrolling version on the 3DS.
It definitely looks better than the first one, at least according to this trailer, but I still have difficulty getting excited. I'm tired of Disney fiddling around with these so-so Mickey platformers. They own Pixar, Star Wars and Warren Spector now--they need to put him and Junction Point studios on something natural like Tron.
