Linux Gaming

I'm looking for discussion and suggestions about the best way to play games from GOG on linux.

My current method is that I've got GOG Galaxy installed with bottles, and then I use GOG Galaxy to install and launch the Windows games. That's working alright so far. One downside is that won't install Iinux versions like that, so for games that have a native linux version I have to decide if I want to install it separately, or just run the windows version with the others. So that isn't perfect. Another minor thing I don't like is that since I'm installing games via GOG Galaxy via Bottles via Flatpak... I end up having very little idea of where stuff is being saved. It's difficult to find save game files for example; and if there is some junk installed or left over from something, there's very little chance that I'm going to notice and delete it. It just feels very opaque. (I guess that's mostly just about my personal lack of knowledge though.)

Anyway, I'm mostly just wondering how others are choosing to handle their games from GOG.
