Okami - The game back in the PS2 era was essentially made to be done on the Wii U now. I never played the handheld spinoff, but I loved the original.
Banjo-Kazooie - I feel the 3D platformer genre has mostly died off these days and it would be great to see a proper return of the fun, colorful, 3D platforming that BK use to do. Parts of that was in Nuts & Bolts, but the main chunk of that game was racing and building and not proper world exploring. Conker can be included in this and it was a weird mix of excitement and disappointment when Conker showed up for Project Sparx on Xbone lol
Brutal Legend - I'm happy to see it was brought up already, but I LOVED this game. It had it's issues with the RTS aspect of the game, but I loved the setting, I loved the music, I want endless games from this world. I want Brutal Legend 2 through 10 right now!
Mega Man Legends - We almost got it, but sadly no.
Fallout - I know it's coming eventually, but I REALLY want it lol
