So I've encountered a weird situation lately.
I stated playing Banner Saga 2 on GOG and encountered a major bug. I went around searching and found that it's a known bug but there were no new posts about it anywhere. Old posts didn't have much of a solution on the other than 'Wait for a fix'. I posted on GOG forums for Banner Saga but frankly there's nobody there, so I went and posted the same problem on Steam Discussions.
Turned out that this bug was fixed on Steam A MONTH AGO but that build has not made it's way to GOG yet. Their moderator has told me that 'pushing builds with hotfixes on GOG is not as easy/streamlined as it is on Steam' and that 'it might cost the devs money (directly or indirectly) to push new builds every so often.'
I'd understand if it took 2-3 days or even a week for an update to go live on GOG but a month is just bullshit.

Is any of what he said true or is he just trying to bamboozle me so I won't blame the devs for this ? It seems to me like they are just ignoring GOG customers. Before the game came out it looked like it wasn't gonna come to GOG at all because 'PIRACY' and now this ?
Who's the problem here ? GOG or the developer ? What is even going on ?

Sounds like BS to me, seems most devs just don't want to keep GOG versions up to date.

Why would it be an issue though and why would it cost them money?

Smells fishy.

As Emachine9643 says: Why would it be an issue and why would it cost money to bring the same build here?

Unless proper explanations answering these questions are given, consider yourself bamboozled.

If you get more information about this, please do share it here. As someone who enjoyed TBS and might get TBS2 I'm interested on what they have to say.

It is true. Valve has been doing this for about 13 years or so, so their technology is greatly ahead of where GOG's is at the moment, and unfortunately this puts a lot more burden on the game developers. GOG has spoken about this in the past both here in the forums and in interviews mostly talking about Galaxy. The inefficient update system is one of the reasons why more games do not come here and thus a big part of the motivation behind getting a better update system built into Galaxy.

The Steam update system from what I understand allows developers to directly push their updates to customers without Steam needing to be involved in the process. Steam's updates are supplied as compressed binary deltas to reduce downloading to an absolute minimum, and Steam doesn't provide other options for downloading games or updates so it is very efficient for developers.

GOG on the other hand has always provided customers with standalone installers and separate patches, so the developers have to provide GOG with a special build which GOG then takes and packages their installer around. There's the extra work of the developer to prepare this for GOG, then the work GOG needs to do to prep it and test it and make it available for download on the website.

GOG is developing their own update system within Galaxy that will eventually work similar to Steam's delta updates, however they appear to only have the delta updates in place for select newer games that are receiving updates regularly. I can't be certain but I do not believe delta updates are available on Galaxy for all games yet, and probably wont be available for a long time as things seem to proceed very slowly on this front.

I'm not sure what all extra things developers need to do to prep updates for GOG for the Galaxy side of things, but GOG will always have to prepare the old style standalone installers and patches as that's a core feature of their service and they've advertised Galaxy from day one as being optional, so they'll always need to make updates available the old way.

What they need to do, is figure out how to automate the entire process as much as possible and make it as easy as can be for developers in order to cut out the extra effort they need to put into updates currently as well as cut down on the lag time between something being updated on Steam and the updates making it here to GOG - if they ever do.

Some developers sell their games here and rarely if ever bother providing updates. See the "second class citizens" thread for details of the problem and which games and publishers are the culprits.

I think it is also fair to say that even though GOG owns part of the problem for not having the easiest update system for developers to use, the developers themselves choose to sell their games here and then choose to not update them and that is disingenuous to their customers that buy the games here. They should either take on the extra work as a part of signing up to sell their games here, or they should pull their games until there is a better update system. What they shouldn't do is treat their customers as second class citizens by selling their games here and then never supporting them, that's just dirty business IMHO.

GOG of course is "working on it", and I'm sure they mean well by that, but it could be 1/2/5 years before "it" is actually "working" as some things seem to take a very long time between "working on it" and "works" here, and this seems to be one of them.

Thanks for the detailed info, it seems you really did your homework on this.

Is there a place that monitors the worst offenders in the update lag?

I don't mind waiting a couple of months for updates, but never...

EDIT: Ah, found this: https://www.gog.com/mix/games_that_treat_gog_customers_as_second_class_citizens

Frankly I don't see, how they are going to do that. At least so it would be as simple as in Steam. Because, basically Steam dev can push update and if something goes wrong pull it back the same day. And all users, connected will receive the latest patch automatically. Even if GOG will store the latest version somewhere in their storage, users would have to download the whole thing if they don't use Galaxy.

They're not limited to doing what they do now, they can always adapt what they do to make it do what they need it to do. Just because they don't currently do something doesn't mean they can't do it to morrow. They could easily provide multiple releases and effective rollbacks for direct download if they felt that was an important or necessary feature to have. Galaxy itself does have support for rollbacks at the moment. It would require some retooling and work to make something available for standalone builds to do that but it's not impossible to do, and it's something most likely that can be fully automated. "GOG Rollbacks(TM)"

TL:DR

GOG checks to see if an 'update' is bunk before posting it--Steam does not.

YMMV

Except, the version that's out now is the bunk version...

Besides, with Galaxy being created around devs being able to push out updates without GOG having to be a middleman that is clearly going out the window. Automatic + the possibility of rolling your game back if the update is bunk is the best solution imo.

I'm at Gog precisely because they don't auto spam the entire world with forced updates that make your game unplayable until you download it.

Google: "expectations"

then google; unmet expectations; 'WHY?'

then google, "if my existence is so unimportant; then why do i exist?"

consider ends not means.

take action!

The world gets better????!

Google: "boring"

So what about users who don't want to use the client? All I see above is how things will get better with the client?

Well, considering they still need to make installers for users that don't want to use the client it will probably be business as usual.
