Is Rayman Legends the first game that got released in it's original edition for both 360 and XB1 that has gotten BC support? It's kinda of strange seeing 2 copies of the same title on XB1. Not that I'm complaining! It's one of my favorite games, and because of the kind of title it is I could see people who owned it on 360 not wanting to rebuy a pretty similar looking version to play on their XB1.
There is Limbo too.
I find the absolutely great because it shows they don't just release games to make money but so that gamers can play THEIR old games again at no cost without buying the new version.
