I have looked around these threads, but still have not seen explicit answer to this question, so I figured I'd make a new thread.
After you insert a compatible 360 game's disc and download it, do you need to keep the disc in the Xbox One to play it, or is it available from that point forward 100% digitally? (i.e. no disc required after initial download)
I could see the system being exploited if the disc were not required to play after initial download, because what's stopping me from buying a used, compatible 360 game from Game Stop, putting it into my XB1, downloading the game, then returning the game to the store.
Another question: will any Xbox Classic (XBC) that were playable on the Xbox 360 be made compatible for the Xbox One? Xbox.com's official list of XBC games playable on the 360 (http://support.xbox.com/en-US/xbox-on-other-devices/original-console/play-original-games) includes a whopping 460 titles. Many of them are much loved classics (my personal favorites are SWBF1, 2, and KOTOR.)
I'm wondering if there is any technical limitation to bring these titles to the Xbox One. In my mind, because a version existed for those XBC games that worked on the 360, it can be treated like a native 360 game and brought to the Xbox One as well... but I'm no Xbox engineer, so I could be dead wrong!
Does anybody have any clarity to offer on either of these two questions?
