If your post is only relevant to one hardware device (Deck/Machine/Frame/etc) please specify which one as part of the title or by using a device flair.
These are not enforced, but they are encouraged.
Rules:
- Follow the rules of Sopuli
- Posts must be related to Steam Hardware or Steam OS in an obvious way.
- No piracy, there are other communities for that.
- Discussion of emulators are allowed, but no discussion on how to illegally acquire ROMs.
- This is a place of civil discussion, no trolling.
- Have fun.
Disclaimer: I haven't tried it.
BUT: I'm both a Deck user and Linux desktop gamer. I believe you should be able to install Epic and GOG both (the launchers) as non-Steam apps, and then they each get installed to fresh Proton prefixes in Steam. No additional tools should be needed besides Steam itself.
I think you can still select a default install location for their games too, since you do get Linux file system access from the prefix (it's mounted as drive Z).
I'd probably run them both using Proton Experimental, since it tends to be better with other launchers. Or, a later version of Glorious Eggroll. The cases where something doesn't run on GE or Experimental (but does work with some other Proton version) should be extremely minimal, so using one of those for the whole shebang should give good results. You can freely change the Proton version for the whole launcher if something gives you trouble.
Yes there are other solutions (Heroic, Lutris), but ultimately this should work as well with fewer components. I use this approach for Ubi games that use their daft launcher.
