Microsoft is winding down new additions to its Xbox backward compatibility catalog. After adding more than 600 Xbox and Xbox 360 games to the list, the team is now focusing on Microsoft’s next-generation Project Scarlett console.

Microsoft is now committing to get every Xbox One game running on Scarlett, alongside games from all four generations of Xbox. While the catalog of old games might be finishing, Microsoft is adding a lot of games as it looks to move toward Scarlett compatibility. Old Xbox classics coming to backward compatibility include:
