Xbox One and, by extension, Series X|S, sport backward compatibility, letting you play earlier generation titles. It's not just 360 that benefits from this but the original Xbox too via emulation. Modern Xbox can run a virtual 360 and the 360 supported native backward compatibility, meaning that you can play original Xbox games through a 360 emulator on a One or Series X|S. Does your head hurt? Don't worry.
To put it plainly — you can play original Xbox games on your newest hardware by putting in the disc, buying them digitally, or even by launching them through Xbox Game Pass. It's pretty simple.
With that said, here is the extensive list of every original Xbox game that you can currently play on your One or Series X|S, including the titles available on Game Pass.
