You could run Steam for games without native ports and see how Proton handles your games out of the box. Another option would be ./play.it or Adamhm's wrappers, as mentioned by vv221. I've tried one of the latter and as a complete Wine illiterate myself it worked like a charme and the setup was very painless as long as you can follow instructions. Similarly, DosBox and ScummVM are native, so using innoextract you should be able to run respective games, as well, though that's a bit more fiddly.

As mentioned by Punington, Lutris would be another option. You get to import your GOG library and game installation is handled via user scripts, so you might actually get your Windows games with pre-configured Wine/DosBox/ScummVM setups. Well, there are some games without port due to the lack of Galaxy and I'd think we would get those. I'd wager a guess that's not going to cover your entire library, though. As far as the rest is concerned; Steam already exists for Linux. If that doesn't entice developers to port, I don't think Galaxy will, either. Especially since - though I do not have the numbers to back this up - I would think Valve already has a much bigger customer base among Linux users - especially since we don't have a client here.

So essentially you can try to make due with the options you have on Linux, accept that not all games are available here, or stick with Windows. But if you don't want to switch without a GOG client that runs your entire library, I'm afraid that choice has already been made for you.

It does but not all games are available through Lutris due to lack of WINE wrappers. Plus sometimes Lutris error's out on GOG installs such as erorring and removing the install or going into an install loop (there are my own experiences with Lutris).

It is possible to install Galaxy using Lutris then installing games through the Galaxy client.

I'll have to check it, but unfortunately the official 7-zip application has some very nice features I like, like the ability to test all or several archived files (be it 7z, rar, zip, an self-extracting exe, or whatever) in the current directory for their integrity. Hopefully file-roller has that too, as I recall that e.g. PeaZip (which supports 7-zip archives as well) didn't.

As I said, some things are still easier and more natural in a graphical user interface, while some are easier and more efficient in command line. Depends what you are doing.

For instance, if I want to compress a subdirectory into a 7-zip archive , with the 7-zip application it is two mouse clicks (right click on the subdirectory, and left click on "7-zip => Add to archive subdirectory.7z". Sure it can be done in command line as well, but it is still quite much more typing I think. This starts mattering if there are e.g. a couple dozen subdirectories in the current directory that you want to compress into archives.

Or, another example is that sometimes I want to compress only certain files in the current directory into an archive. It is much easier to select the files with a mouse, than trying to write their names in command line.

But if I work in command line, yes I very much prefer doing it in the bash shell, than in Windows command prompt or PowerShell.

I... think I checked that earlier, but the point is at the end of that page:

"If you currently don't have a commercial Office 365 subscription, you can still try Microsoft Teams for Free."

And when I check that "MS Teams for Free", I don't see Linux listed there. It appears to be available for Windows and Android/iOS.

I wasn’t aware of MiniGalaxy. This is really cool for native linux games. Thanks for sharing this. I fired it up, seems to work fine. If your new to Linux, Lutris or Crossover could be your new best friends as others have mentioned. So far I’ve had a decent success rate on getting my Windows games to run, with low effort on my part. I was using a Windows 10 VM for Galaxy downloads, but with MiniGalaxy that won’t be needed now.

I appreciate all of the suggestions! It's nice to see that there are so many options available, but I'm not sure if I'm ready to move to Linux at this point. I'm sorry to say that I'm a slave to convenience, so if I can't get it to work 'out of the box', then I might as well wait until Galaxy (and my gaming library as a whole) works on Linux. Although I might be waiting for a long, long time.

Compressing a subdirectory is a simple command in the shell, and while there's a little typing, it has the advantage that you don't need to figure out where to move the mouse, and to then actually move the mouse (which is annoying to do if you're on a laptop with a trackpad instead of a mouse, or if the mouse isn't working well (and I've had more problems with mice than with keyboards)).

If there are a lot of directories that you need to compress, you can automate it with a script in the command line; you can't do that easily with a GUI.

To be honest, even working with the boxes, it isn't that complicated. Test drive a few distros and ignore suggestions based purely on the Desktop Environment (you can just install any of those.)
