PC/Linux/Steam Noob here. I just got a game from GOG and I’m seeing tutorials mention Heroic, Lutris, and Wine via ProtonUp-QT as methods to get non-Steam games installed and running on Deck. Which method would you consider the easiest and most reliable for content from GOG, Ubisoft, Epic, etc…

Follow up, here’s what I did:

1. Desktop Mode: I installed Heroic Launcher (it handily chose a location in my games folder), and added it to my steam library.
2. Game Mode: I did the change artwork stuff for Heroic, booted it, signed in and all that jazz, then installed and launched the game (Lost Ruins).
3. Desktop Mode: I navigated to the (Lost Ruins) game folder and found the “start.sh” file that boots the game, then added that one to steam.
4. Game Mode: Did the change artwork stuff for the game itself, and now I can add game-specific settings for it.
5. (Extra) I added a “Heroic Launcher” collection to store GOG & Epic content.
