I have both an Xbox One and an Xbox 360. anything bought for the one, will not be usable on the 360, and what's bought for the 360 isn't usable on the one. I have a total of 4 Xbox 360's and 1 Xbox One in my house hold. And this same reason is why I only bought it on the one this time around. I , or anyone else for that matter, shouldn't be forced to buy this content several times over. yes I have in the past, but just because not all my friends can afford an one, just because I bought one. I'll eventually buy it for my 360, but not just yet.
