What a nasty, mean-spirited thread.
That being said, Super Mario Galaxy 2. I want it to fail becuase it has some badly implemented motion controls and then Nintendo will realize that the Wii-mote is great for a few things, but Mario needs a controller and they will make a new Gamecube style controller for their next gen system and the Wii-mote can be an add-on for the sports games. In my perfect world that is.
But this is just a mean-sprited thread, and you should all be ashamed.
