> While I like GOG, I must say that they don't support linux, they merely sometimes make it possible to download binaries which may work on linux if you do everything yourself.

They have an actual "Games for Linux" section (https://www.gog.com/en/games/linux). I guess that should mean anything more than just "this may work on Linux if you compile this kernel and use this version of wine with these patches".

Yeah, that's a LITTLE more support. I didn't found this section when I was seaarching for some games, but then I'm not an avid gamer.

Can't you just download the Windows binaries and use Proton, just like with a native steam game?

I tried, but not every game works out of the box yet. Sometimes you need to do a lot of work to play a game on linux, on windows you just click "next" several times. Also, they don't provide linux launcher, you first have to find that you can indeed download those games manually, navigate to your library in a special way and then you can download something that might work.

Lutris helps significantly with this

Thank God for lutris
