The Wonderful 101. Loved that game so much.

ZombiU, very fun survival horror with a great multiplayer mode.

Since many people are mentioning them, I also had a blast with games like Wonderful 101, Hyrule Warriors, Nintendo Land and Zombi U, tho all of them are on the positives with their reception (75+)

Devils third. Felt like a game that just needed a few more months to polish the levels and get it all together. Still enjoyed it quite a lot, despite its many flaws

Hyrule Warriors is pretty much it for me.

Pretty much all of my Wii U games scored well, but if 76 is considered mixed, then Hyrule Warriors.

Hyrule Warriors and Nintendo Land if 76 - 77 is considered mix reviews :p

w101

Most obvious is W101 which imo the reviews are only mixed because of how technically skill based the game is, it's a game you hone your skill in over time but the high technical ceiling would mean that it's more for mid to advance action players which is a very niche group. If you're not in this group it's hard to enjoy.

Project Zero 5 is the other game.

Recently beated One Piece Unlimited World Red. Great game for a One Piece fan like me, a lot of stuff to do, a lot of characters to play, the game's visually cool. Only flaw is the battle system who's the same as in muso but the game's more of a closed arena BTA than a true muso.
