Well, E3 is well underway, and there have been quite a few Wii U games announced already, ahead of Nintendo's own presentation tomorrow which is said to be focused on games rather than on hardware. (Nintendo quite nicely got all that out of the way yesterday with a special Nintendo Direct video.)
On the top of my radar is the new Rayman Legends, which promises to be a crazy multiplayer platformer that will be a strong title for Wii U. It's looking even better the more I see of it! Next would probably be a quirky eShop game called Chasing Aurora, from Broken Rules, the developers of And Yet It Moves.
We'll just have to wait and see what Nintendo talks about tomorrow. I'm hoping for a crazy Monster Hunter 4 reveal, but that's just me talking crazy!
