Two of my favorite games from the 360 are available on the One, but only if I want to purchase them again. The first was Marvel vs. Capcom 3. They re-released it rather than making it backward compatible, which ticks me off because they'll be releasing a new one within the next year or so. The second was Street Fighter IV, which was made backward compatible but only for the basic version. I have Super SFIV Arcade Edition and when I popped it in to download it, it said that this game isn't available to be played. Really ticks me off!
Just needed to rant.
