Never gave the Rayman series that much thought; I only played Rabbids once at a friend's house.
Since I like the Skylanders, I might give the Rayman: Legends a serious play for the Wii U. It would've been nice to see a glimpse of Ezio, though, in-game.
I wonder if Nintendo is going to implement the NFC features with Super Smash Bros: Wii U? [EDIT] or Pokémon for Wii U, with NFC features!
