well, my "list" of games to check out on wii U is 23 games, so it's not terrible.
It's on the same level as the N64.
side note - f*ck Mario Maker, With no cohesive goal, I played it once and that was good enough for me. Never really gave me a reason to play other than just getting more of the same.
Did you look at Hyrule Warriors? It's pretty Dynasty Warriors-y, but I had a good enough time with it.
another one to look at is the NES remix pack, not for everyone, but I'd look at it if you haven't.
