I mainly stream games from my desktop via Steam. Is there a good software to manage my non-steam games so I can play them remotely via Steam (to automate the process of adding the games/launchers to Steam)?
Not a manager, but if you're adding non-steam games to steam I do have a guide that might be helpful. I originally wrote it for r/steam_link but re-posted it into Lemmy yesterday.
I use lutris and heroic for non stean titles since last i checked they both have a feature to add games to steam. and steam rom manager for emulators but for games that just arent on any stores like starsector i just add them manually and use plugins for game art
