DRM-free multiplayer, and the communication of it on the store page, is basically my only gripe with GOG right now. Sure, lots of things can be better, but this is the thing preventing me from shopping with them friction-free. In my mind, any game using the Galaxy API could be pointed to a locally hosted replacement instead so that devs who don't want to, or historically didn't, design with LAN in mind end up getting fully offline multiplayer on GOG with no extra steps for them. At least it's on their roadmap. I hope we see some progress on this front in the next year or two.
