Point_Man: According to GOG updating at least the Galaxy version is just as easy as updating on Steam. The extra verification they do afterwards is to add the update to the downloadable installer version.
nasKoo: Doesn't mirror our experience. It's currently awaiting approval. The conversation we had was that once this is out, we can publish updates to the master branch as they come without waiting for approval.
we do have a devportal open to all our partners, not only for those who are implementing Galaxy features. Within this portal every developer can get a hold of our build delivery tool that works exactly like steampipe - updating a game on GOG is a matter of executing a single script.
So maybe it's an option not every developer is aware of? It's strange because you're not the only devs to say this yet GOG claims they have a system in place that works just like Steam... Don't know what to believe at this point.
