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.
It’ll be loads easier. The Lutris installer is set up to automatically handle an error that Battle.net throws when you try to launch it, some BS about the way they package their QT platform. It’s just a terminal command away from being fixed, but future updates run a real risk of breaking it again. It happened to me, and I spent ~30 minutes trying to get it to work again before I gave up and just… Reinstalled the damned thing with Lutris, and it worked like a charm.
Speaking of Diablo, I got a notification while I was typing this message… 😂
