If Rayman legends would have stayed a Wii U exclusive, would it have helped the Wii U as much as Pikmin 3 did?

Honestly the game is superb and speaking for myself it would have been the biggest reason for me to buy one so far. One the other hand, Rayman isn't a big selling game so it wouldn't had that much of a mainstream appeal for the average guy.
