I don’t know either, but I don’t mind, and its up to them.

Adding a bit of info to my comment: With lutris all I did was playing non steam games. Added an executable, set the wine version to GE or something, and used lutris lutris:rungameid/12 or something like this with a flag that didn’t start the GUI (can’t remember now).

Now all I do is:

#!/bin/bash
export WINEPREFIX=$HOME/Games/game-data/battlenet-wineprefix
export PROTONPATH="$HOME/.steam/steam/compatibilitytools.d/GE-Proton10-33"
umu-run "$WINEPREFIX/drive_c/Program Files (x86)/Battle.net/Battle.net.exe"

This is just the basics, I like umu-launcher better, because I have longer scripts that set a lot of env vars, and do other stuff before starting the game. I guess lutris can do this too, but I’m not familiar with it, and its easier to do for me in a bash script.

I found umu-launcher because of this whole AI included into lutris drama. While lutris has a whole gui and everything that I don’t use, I feel like umu-launcher is exactly what I need, nothing more.

My guess is that some people have grown a little to attach to lutris. I’m not acustom to this kind of behavior inside the linux comunity
