The only games that I've actually purchased and/or played from this year that I can recall is Splatoon, Majora's Mask 3D and Mortal Kombat X. I also just bought Wolfenstein: The Old Blood today but haven't got around to playing it.
Splatoon is great, it lived up pretty well to what I wanted, although I admit it has some design issues that really annoyed me. But I still enjoy it and am glad that it has found success (a Wii U exclusive, new IP, being on the NPD charts two months in a row is pretty insane).
MM 3D was a remaster/remake of my favorite Zelda, so there's that.
MKX was fine. I enjoyed it as much as IX.
EDIT: Oh, and I forgot Revelations 2! I was thinking it was last year for some reason, but I enjoyed it a good deal, a very pleasant surprise. Probably my favorite RE title since 4, and I say that as someone who enjoyed both 5 & 6.
