Microsoft is testing the integration of games from various digital storefronts, including Steam, into its Xbox app for PC, creating a new aggregated library accessible on the upcoming ROG Xbox Ally devices. This feature is available to Xbox Insiders in the PC Gaming preview starting today. The library will include titles from platforms like Battle.net, Epic Games Store, and GOG, allowing users to view all installed games in one place. Users must join the PG Gaming Preview via the Xbox Insider Hub to participate in testing. Additionally, the Xbox app for PC will introduce a new section this month for better game discovery, featuring games from Microsoft and third-party publishers on Game Pass.
