I have Child of Light, Abyss Wii U, Nano Assault Neo, Scram Kitty, Runner 2, Trine 2, NES Remix, UNEpic and Pokemon Rumble U.
3D movement would be nice but that's pushing it since that's such a development investment. I dunno, Nano Assault Neo and Pokemon Rumble U are satisfying but lack a bit of depth. Wacky titles like Liberation Maiden that aren't really long but present a variety of challenges and unique gameplay would be nice. Actually, just original content would be nice.
I have heard Squids Odyssey is pretty good but I'm hesitant. Most new releases look equally bland.
