The Xbox One backwards compatibility feature has been popular with users since it was announced, and is quickly making more games available on the console.
(Not to be confused with Rayman Legends that has been available in the Xbox One store for a while.)
Rayman Origins, the 2D platformer that Ubisoft Montpelier released back in 2011, is now available on Xbox One.
Because of the Xbox’s backwards compatibility function, the game has been ported to the One from the 360 for no additional cost.
