Microsoft is finally addressing the lack of retro games on Xbox Game Pass, launching a new “Retro Classics” collection with 60 titles. The service will include a mix of Atari-era games, such as Pitfall Harry, and older Activision titles like Tony Hawk’s Pro Skater. While some may prefer other services for retro games, this addition is a promising start, with plans to add more Activision and Blizzard titles in the future, potentially reaching 100+ titles.
