Heroic Launcher can download the game files for you and any dependencies, including Wine/Proton/etc. You basically install the launcher (can be available from your distro's repository), use your GOG login in the app and it shows your library. Then click install and it'll download the files locally and after that you play the game. The experience is more or less the same like in Steam, at least as far as downloading and playing games is concerned.

I normally download the offline installers and use them with UMU Launcher (which is Proton without Steam, mainly meant to be used as a backend for projects like Lutris, Heroic, etc but you can use it directly from the command-line) but i just tried Heroic Launcher and all i had to do was run it, enter my GOG login and after it downloaded my library info, i was able to download and play a game the same way as in Steam.

I'm not sure what official GOG Galaxy for Linux would add here TBH.

I was not aware of that launcher, thanks.

Two major things:

* Backend Galaxy support for Linux builds

* Multiplayer, achievements, cloud saves, etc. i.e. proper integration with optional GOG services for Linux versions.
