I haven't played through it yet, so I can't say for shure, if you unlock something at the end, but so far I cannot choose whether I want to play as Rayman or Murfy in Murfy-levels in the Wii U version. On my last appointment at Ubisoft, this option was there in the Wii U version and the Ubi employees told me, it would be there in the final version, too. I find this rather scammy, because if it doesn't unlock, as a Rayman fan wanting all the gameplay you can have in Rayman Legends, you now need three versions of it:
Wii U for multiplayer with Murfy and several characters
Vita for exclusive levels
PS360 for No-touch-versions of the Murfy levels.
Did Ubi really change this just to make loyal Rayman-fans pay thrice for the same game?
