Zelda of course, but I will be picking up Fast RMX and Snipperclips day 1 on the Eshop and wouldn't be surprised if I end up spending more total time playing those games since they offer fun local multiplayer.
Zelda is one of those things you beat and then don't go back to for quite a while until you've forgotten it a bit (at least for me), while the others I can go back to every other month
I also only ever tried Shovel Knight on PC so may give it a shot on console
