rjbuffchix: This may sound like a stupid question, but re: GOG offline installers Windows versions, is it possible to use them in Linux and thus play the "Windows version installation" of a game but in Linux? (as opposed to downloading and running the Linux version offline installers).
Time4Tea: I play most of my games by running the Windows version in Linux (using Wine). Most work fine out of the box, but a few require a bit of tinkering here and there.
Thank you very much. That makes sense...I just wondered if maybe I had overlooked something or it would be too good to be true.

SitcomAntibody: Yes.
Every one of my GOG games is installed/downloaded like this. I also use "lgogdownloader" for convenience to automatically grab all the offline installers.
Depending on your comfort level:
a) You could use Lutris, which will also download those installers for you and setup the game. Although, it might be a bit buggy. Cloud Saves are not supported, but you'll see all your games within Lutris and can select which ones to install.
b) You could use Heroic Games Launcher, which again you can login to your GOG account so that it downloads and installs the games for you. Although, this one supports Cloud Saves.
c) You could just download the offline installer, and install them manually using Bottles, but this requires a fair bit more tinkering to get it right. (But it is my preferred option)
The advantage in any case is all the current work being done for Steam Deck to make games work, also applies to any standard Linux install, so whether you're a steam user or not, you'll benefit with all the work.
Basically, if you see "Verified On Deck" on steam, that means it'll work great on a standard Linux computer as well, as none of the work is specific to Valve / Steam and doesn't require using them.
Thank you as well for this awesome response. I appreciate the detail and different options you point out! I hadn't even considered the Steam deck-Linux connection (that is how little attention I give Steam) but that makes perfect sense to monitor the "Verified on Deck" to know for sure it will work great with no extra work.
