Senteria: Oh boohoo, a patch is 1 or two days late...
PersonallyI don't see the problem at all. Least it's being double tested to make sure it all works. If you want patches to be available as soon as a developer uploads something, risking having your game broken, go for it.
On the other hand, I think GOG should have a system like steam where a dev can upload their patch and automatically have it brought to consumers. At the consumer's risk. An official GOG patch can then be released the following day. Also I believe steam has a system where you can add games bought outside of Steam.
Anyhow, people need to learn to be less impatient.
One or two days is fine for singleplayer games, but it's not okay for multiplayer games. Not being able to play coop in the evening due to a new patch being a released on Steam before GOG (Divinity OS) is extremely annoying, even a delay of 1 day is way too much in these cases (and don't forget that Stardew Valley is going to have a coop mode).
It's time for the patching process to change (such as direct updating via Galaxy, patch installers via manual download).
