I think one good one is Affordable Space Adventure on the Wii U. I had so much fun playing that game with my friend. It had such a great use of the gamepad, visually looked impressive, and the overall story and kind of lore it was going for was witty and a added plus. The gamelpay was just great and was a fun puzzler. Its a shame we will probably never see a sequel to that game or any game like in the future.
Totally agree. One of the most unique co-op experiences I've ever played, right there with Star Fox Zero. Too bad that with the dead of the Wii U and its Gamepad we won't see a game like ASA never again...
To me... I think it has to be Wario Land: The Shake Dimension (Wario Land: Shake It! in the US). Not only the Land series has fallen into obscurity in favor of the Wario Ware series, but for the few people that still talks about Wario Land, Shake Dimension is too often forgotten. Which is insane, because to me its easily the best in the series. The platforming and puzzles are great, the level design is pretty original, it has far more content than any other Wario Land game and the visuals and music are fantastic. It's one of the Wii's little gems ^^
