Until my Wii U bricked, my daughter's favorite (and the one whose concept impressed me the most) was the Yoshi Fruit Cart game. Awesome. Something that I would have never thought of. My kid loved it until she got to the 5th or 6th stage (the one with, like, 20 holes) and her mouth just dropper wide open and she said "Dad, I can't do this." Maybe that was a little too steep a difficulty incline, eh?
