Well, you'll be disappointed to know that only a handful of XBOX 1 games can run on the XBOX 360 and secondly, the game must be of the same region. Sadly, most of my XBOX 1 collection are NTSC/U so they don't work on my XBOX 360 NTSC/J because of the different region. It will be nice is companies like Action Reply can come out with some sort of bootloader for the XBOX 360 so that we can play games from other region on our console.
