There's a really known franchise that didn't appear on Wii U (not a new game, at least):
Wii Sports.
Tennis, baseball, box, archery, golf, power cruising, etc.
All this games could work on mobile devices - along with new ones.
It's a very know franchise that has a lot of potential and on mobile it could do wonders!

















Shouldn't be too long considering they said their first game would be released this year.
