These are the first 13 games you can play on any Xbox One if you own the title, beginning tomorrow:If you still have your original Xbox disc, just insert it into your Xbox One console. If you own it digitally, that will also work. Many of these games can also be purchased from the Xbox Store in digital form for $9.99.

“ For titles that support System Link multiplayer, it still works – even across the Xbox family.

I also got to play a bit of Star Wars: KOTOR, Ninja Gaiden Black, and Fuzion Frenzy. All three looked clearer and crisper than ever thanks to no longer being restricted to 480p (or for many at the time, 480i) resolution. Most still run in their original 4:3 aspect ratios, though Ninja Gaiden Black natively supports 16:9 widescreen so it looks particularly modern.

“This detail has always been there, but the technology of the day was holding it back,” said Xbox principal software engineer Eric Heutchy as he pointed out the orange bill and black outline now clearly visible in 1080p on a duck icon in Fuzion Frenzy’s “Twisted System” minigame. "Forgive the clunky tutorial start," KOTOR lead designer James Ohlen told IGN with a laugh when asked what advice he'd have for players trying KOTOR for the first time. "It's definitely a product of his time."As for what original Xbox games will be brought forward next, the team is being careful to keep expectations in check – though they have a good reason. “A curated list of key games was the way to go with this,” Xbox platform lead Bill Stillwell told IGN, noting that many original Xbox game publishers either don’t exist anymore, or the contracts are missing (because they were done on actual paper!), or there’s a licensing issue with a particular song, etc. As such, while it might be technically possible for Microsoft to make them compatible with Xbox One, it might be legally impossibly or unfeasible.
