Not counting stuff like Amiibo Festival, there's also Kirby and Starfox. And Nintendo Land...?
But yeah, it's slim pickings at this point.
Well, Nintendo Land is technically impossible, since it relies too much on separate interaction between the Gamepad and the TV.
Amiibo Festival reminds me that Nintendo really could make some game which is technically free-to-start (as they prefer to call free2play games), but needs Amiibos to work. Could actually be tied together with some Captain N revival, since that one also visited so many different gameworlds as you would with the amiibos...
