The Professor Layton Series on Wii U!!!!!!!! I love the art style they use in those cut scenes, so it would be nice on a bigger screen. Also the puzzles can be viewed on the big screen, where your friends can help you solve it.
And i agree with Luigi Mansion. On the game pad it can have like a first person view.
Edit: I also think Nintendo Land on the 3DS would be nice. With Local and Online multiplayer. And they can do like in Mario Chase, there can be like 2 players are mario, while 8 players are the catchers, then the map would also get bigger ( like in luigi mansion )
Pikmin 3 on 3ds is nice too. But the graphic quality would really go down. Wonderful 101 can also work.
