With the use of Heroic game launcher, I’m wondering if you all preferred to play your GOG version of games over the Steam version. I can go either way but sometimes I pause and think, having two copies of the same game, one on steam and one on GOG, which one would give me a better gaming experience. For example, I may choose the GOG version because I don’t have to deal with pre-shader work being downloaded every so often. I can just into my games. Yet, Steam achievements and seeing the game’s metadata is always life: seeing the game info, store page, community stuff about the game, and more all there. So what do you chose? GOG game or the Steam game.
For me it’s GOG first. Using lgogdownloader and wine directly (in a custom apparmor profile). No DRM, no forced updates, no annoying client that takes forever to start. Games are also dramatically much easier to isolate and sandbox this way.
If the game is not there, then yes, Steam (as a separate unix user).
