Worried about the Murphy discussion with Rayman Legends? Don't want to play as anyone but Rayman? Sounds like you have nothing to worry about. Rich over at IGN was asked if it was possible to play the entire game without using Murphy. He was also asked if you can play without the GamePad. Rich simply answered 'yes' to both questions.
I'm definitely playing GamePad, but it's nice to know the Murphy aspects are completely at your discretion.
