Historically I’ve used lutris but more recently I’ve been observing more broken scripts than not. But Lutris is extremely handy for mapping to a pile of game data that I might grab from Itch for example. I also havent been gaming as much lately so maybe I’m just hitting some weird games and that’s all.

I’ve heard good things about Heroic Launcher which apparently is actually sponsored by GOG, but I’ve yet to try it on my Linux machine
