Seems like every week over on GamingOnLinux there’s an announcement of a new launcher.
Personally I only use Steam & Lutris. Lutris for my gog games and BattleNet, Steam for everything else.
I don’t know of a good reason to use Heroic, or any of the other new ones over Lutris / Steam, but maybe I’m missing out.
Lutris and Steam. Also tried Bottles with very mixed results and Heroic Games Launcher that sometimes just works and then sometimes just doesn’t. Never tried PlayOnLinux, is there any advantage to it?
