Okay, I see your point, but I’d still say it’s a better license than Steam’s/Epic’s, because the games are DRM free (unless they’ve changed that and I’m not aware of it) and so once I’ve downloaded them, I can then play them whether or not GOG still exists or my “license to use GOG services” was revoked.

you can run most Steam or EGS games without having their respective clients installed

This is not consistent with my personal experience (though admittedly it’s been a while since I’ve tried – maybe a lot of games on Steam are now DRM free).

I’m using Aegis Authenticator and I regularly back up my list to an external file uploaded to my NAS. If my phone dies (which has happened before), I can then just restore the list from the backup ¯\_(ツ)_/¯

As a clueless gog-game-buying normie, can you elaborate?
