Bazzite is working on a Steam OS-like UI using opengamepadui that has integrations with GOG and others. That team is working on a steam input alternative too.
That would be pretty slick. I just ran a cable from my main PC to the front room TV and being able to use big picture would be nice but I have a game or too on GoG (use the heroic launcher to play them)
The games that live the longest, are shared the widest.
Hello, Doom.
