This would be huge and a big step to single purchase ownership.
One of my biggest griped with the modern state of gaming is how purchases are platform based.
Minecraft pe doesn’t transfer between ios and android yet on pc all my games work on linux the same as windows.
Once we have the power to load the OS where we have acces to our library publishers will rush to make sure their platform gets that access.
Valve really appears as the woke gaming authority that single handed progresses the industry. Someone link a source if that perception is wrong.
