Exclusively Smash 4, Hyrule Warriors, Wind Waker and Twilight Princess should hardly be called that? They're available on 3DS,3DS, GC and GC/Wii respectively.
Based on the actual exclusives I would give it to 2013 just for Pikmin 3 alone, that game will have me buy a Wii-U before this gen is over.
Fancy hearing me on an amateur podcast with friends gushing over one of my favourite games? https://youtu.be/1I7JfMMxhf8
