NonSteamLaunchers is a project to help you easily install various external launchers / game stores on Steam Deck like EA App, Battle.net, Amazon, GOG Galaxy, Ubisoft and more. Recent releases have much improved automatic shortcut creation in your Steam Library.
Lutris and Heroic can both add steam shortcuts so you can launch from steam directly.
Is there any benefit to switching? Right now Heroic works well enough for launching any Epic/gog games I want
I use heroic now, but whatever works best at the time. Wish something would be better at setting/searching controller configs.
On mine, these shortcuts cause the game to run behind the steam loading icon, invisibly. :(
