Xbox is rolling out a new feature that will unify game libraries across multiple storefronts, introducing an "aggregated gaming library" in the Xbox app. This feature allows users to view their entire game collection, including games from various PC storefronts like Xbox Game Pass and Battle.net. Additionally, a "cross-device play history" feature will debut later this month. The updates aim to enhance the Xbox app's functionality, potentially reducing the need for third-party applications for managing games. This initiative aligns with Microsoft's vision of creating a comprehensive gaming ecosystem.
