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.
Okay. You can easily do that with Lutris as well by just adding a non-Steam game. So if that’s the only real difference then I’ll stick with Lutris. Thanks.
