Yeah I’ve had issues playing GOG games on linux using arch/gentoo because the libs that the game wants to dynamically link are often not where it expects. It’s possible to resolve it but the Steam approach where they distribute a static bundle of libs into ~/.local/share is much less of a headache.

Presumably Galaxy could solve this problem and make Linux more viable. The dynamic linking of the libraries has been more of an issue than the missing Proton integration for me. Often it is easier to install GOG games with wine and take the performance hit!
