In 20 years of using Linux, I’ve only had a broken Linux four times. Four of those times, it was because of Windows being shit.

for now… they depend on Firefox. Not sure what will happen once it goes the way of the shit.

I might not know the use cases that Lutris covers. But I’ve been very (edit: happy) with Heroic Launcher for installing GOG games and keeping them up to date, and with entries within steam.
