What is your favorite 3rd party Wii U game? Based on Gameplay, Technical/implementation details (if any) , the effect it has had on you or your friends and any lessons for devs and/or Nintendo if any.

[zippy]

Zombi U and Deus Ex have superb use of the gamepad, the Batman games look great, Need for Speed is technically a very sound game, Black ops 2 is the definitive version with superior Wiimote controls, off tv play and co-op with seperate screens for the players (this is a big deal to me). Also its worth pointing out that multiplat games such as Splinter Cell, Sniper Elite etc dont suffer from awful screen tear the HD twin versions had.
