In July, Microsoft originally launched the idea with just four Xbox games, so 25 is progress, and Microsoft says all these games are now playable with keyboard and mouse.

Plus, Microsoft says it’s adding achievements to original Xbox games for the first time, starting with four games: Star Wars: Knights of the Old Republic and its sequel, Blinx: The Time Sweeper, and Conker: Live and Reloaded. You can unlock achievements playing them on Xbox One and Xbox Series consoles as well, after a system update. More games should get them in future.

Here’s the full list of Xbox on PC games, with the 21 new additions in bold:

Yes, that’s a lot of Star Wars games, most of which already have a PC version, and few games that were exclusive to Xbox at the time. (But many of those Star Wars games were excellent.)

You also won’t be able to use an original Xbox disc to play these games, I’m afraid, as original Xbox (and Xbox 360) discs aren’t part of Microsoft’s disc-to-digital program; they predate the unique serial number that Microsoft embedded into Xbox One discs. In case you’re wondering, Xbox on PC backward compatibility appears to be powered by an emulator.

Also, most of the new games aren’t currently included with Xbox Game Pass, according to Microsoft; just Blinx, Conker, Crimson Skies, Fusion Frenzy, Morrowind, and Grabbed by the Ghoulies.
