So as we know Windows Platform Apps and WinUI3 apps do not work on Linux, I keep wondering if Microsoft were to launch a new API let’s say direct X 15 but limit it to Windows Store Apps, and provided a way for the apps to be installed from other stores like steam could they in time kill modern Linux gaming.
IMO the Windows Store is why valve has invested heavily into gaming on Linux. Windows Store could easily become a huge Steam Store competitor if Microsoft were an effective company. So Valve wants to enable devices that don’t run Windows. Numerous other benefits for something like the Steam Deck as well, but I’d bet we see another Steam Machine someday - probably after they convince more companies to support Linux
