A homebrew plugin, Junk Store, from Decky Loader for Steam Deck, enabling GOG and Epic games on Steam, is evolving into a standalone software release on Steam.
Valve's Open Stance on Cross-Platform Access
Valve appears open to this, allowing users to access games from rival platforms seamlessly within Steam's interface.
Challenges in Transition
Junk Store's transition to Steam involves a cost due to rebuilding and lack of open-source code, necessitating funds for additional features. While approved on Steam, the software faces a complex review since it fundamentally alters Steam's functionality.
Hopes for a Positive Precedent
Developer SDK Innovation hopes this move sets a positive precedent on Steam, yet Valve's final approval remains uncertain, despite its history of supporting innovative projects like Black Mesa.
