I cry about SonyGaf from my chair in Redmond, WA
The reason not every 360 game works on Xbox one is because they are not running off the disk as all. They download a version with a new executable and the disc is just the key if you don't have the digital version.
Well, yeah because bc was an afterthought. Xbox One isn't build around bc and came first later in the generation. So I'm not wrong.
