further, heroic games launcher isn’t just for epic and gog games, you can install any exe. i use it for the ea games launcher because the lutris script was broken at the time. and in the wine manager in hgl settings you can choose either wine-ge latest or proton-ge latest (or whatever number version) as your default layer, which you can also change per game/app if you have trouble.

edit: and also you can set it to add to steam so you can still just use steam as your main launcher, for example on steam deck or using a media center rig in big picture mode.

Also to add, it’s not just for games but any application. Games are just the primary focus.
