Ubisoft have done a better job with the Gamepad than anyone else, even Nintendo

[Asriel]

From what I've played, Ubisoft have made the best use. That's based on Nintendo Land, Wind Waker HD, Mario 3D World, Pikmin 3, Wonderful 101, Rayman Legends and ZombiU, plus digital titles Little Inferno, Trine 2, and EDGE.
