Why not let people know when the patch will be available? People would like to know, especially since on Steam, for example, the BG3 patch was available much earlier than on GOG. Why not inform people?

You mean why don't the game devs notify its customers when the patch will be available?

No, I'm talking about GOG. Even if it's the dev's fault they should inform about it. Do I have to teach them about public relations?

Yes, actually. GOG does need lessons in public relations.

As for "When will the patch be available", roll a six sided die to determine priority, use weighted dice if the game is bigger than normal. Then pick a random number between 7-14. Halve this number if the game is attractive to customers. This time is supposed to be used to test the game, but the testers might be too busy at their indoor gyms, petting dogs, and having expensive fruit from the canteen. Faff around for a while and submit a test result at 14:55 on a Friday. Clock out early, you have tenure.

Now, supposedly, there are mechanisms for expedited patching, but those processes are so poorly documented and advertised on the developer end that many of them have never discovered this.

Galaxywise Hotfix 2 was available at the same moment as on steam.
Offlinedownload wise Hotfix 2 was about 24 hours after the Galaxy release of the patch.
Also regarding offline installer updates gamecard is showing an notification when a patch is available
So dunno?

If the dev doesn't INFORM GOG about an incoming patch, how the hell is GOG meant to inform its users?

The devs are responsible for their own work, and for the most part this is meant to be automated.

Devs aren't even providing blasted changelogs like they should be. Is GOG supposed to hold their hands with every file upload?

Galaxy updates at startup once the patch has been uploaded and released.

Offline installers usually are available later, sometimes not even the same day. When you visit the homepage, you see a blue dot in your library, if there are patches or updated offline installers available for download.
Do you expect a mail or something?

This really is a minor concern in my opinion. They have much more important issues.

Btw, you can see all updates here:

THX bro!

BTW

The most important thing these days is good PR. Toyota understands this and you can check for yourself what kind of PR they have, mainly it's that bad news spreads much faster than good news.

People see that there is a difference between the Steam version and the GOG version, for example, they can't play for a day or a couple of hours together with friends who have the Steam version.

If GOG does not provide information right away why this is happening. Whether it is the developer's fault or some other.

This later leads to a heist and people spread the word that they either won't buy the game on GOG anymore, or no one informs them what's going on.

Such information spreads really fast.

Regardless of whose fault it is, GOG should clearly communicate why this is happening for its own sake, because that's what I care about.

The "why" is the same every time something like this happens: Because the dev didn't upload the game to GOG servers yet.

GOG does not monitor Steam releases. They don't have the necessary informations to communicate a reason for differences.

Some devs are very dutiful, they release on all platform (GOG, Steam, Epic, Gamejolt) on the same day. But most devs release on Steam first, on the others later.

And in sadly way too many cases some stop releasing anywhere but on Steam at some point. There are some games, where the GOG version is several years old, but the Steam version got updated repeatedly.
