Still Breath of the Wild. It outclasses everything else so hard that it deserves to be mentioned in a thread where it shan’t be mentioned. 
But really though. Staying within the confines of the topic I’d say it’s between Super Mario 3D World, Mario Kart 8 and Captain Toad Treasure Tracker which I haven’t seen mentioned here yet. Great game, one of the best puzzle games out there. Though since it’s a small game that’s a spinoff of the a game that already being considered to be a “small” game compared to it’s peers, I’ve got to give this win to Mario Kart 8. An ambitious Mario Kart that will stand the test of time.
