I love my Steamdeck but I've never found the argument for Linux gaming very compelling when it explicitly hinges on running Windows emulator software. It's really just an argument for consoles. PC gaming isn't really a good idea because PCs aren't really a good idea, and with the PCs, the big 3 OSes aren't really a good idea either. Salvage the kernels and build narrow, bespoke things without all the cruft.
