Great game, though I liked Origins better. The main hub and levels don't quite have the same whimsical feel Origins' levels had, the story is also weaker, it's barely there - though likely you're not playing this game for the story.
Rayman and friends feel great to control, the special challenges and stuff add a lot to the game. You can even play levels originally from Origins, though it's not the same to me...
I think the biggest issues I have with this game is with tone and style, it's just less appealing to me than those of Rayman Origins. Also not a huge fan of the soundtrack, where the previous game had an amazing one in my opinion.

I'd personally reccomend Origins over this one, despite Legends technically having more content. But both Ubiart Rayman games are great.
