At least for the next few days until it's finished.

Adventure games however are slow burners by tradition. Monkey Island 1 and 2 were never on top of the charts but made enough money over the years.
On a long term, this messed up launch will be forgotten.

It was mentioned on Discord that this happened because there was a national holiday in Poland on Saturday, which meant employees got a day off on Friday and they didn't have time to get the offline installers done. I am and will always be the first to demand offline installers, but in this case it was just that and it should be sorted out tomorrow. The world is not ending.

Just to clarify - who metioned this? Someone who works for GOG? Because Friday isn't a day off work because of the holiday on Saturday. When a holiday falls on a Saturday, the employer has to "make up for it" with a day off at some other time, but it can be any day, whenever. For example where I work we're getting that day off on December 27th.

That feels like skewed priorities. How long should it take to prepare a install builder? Maybe 15 minutes if you have version control systems properly set up? Shouldn't be as automatic as can be?

That's all true ... and some time to test it. And that's why that day about 15 games got installers.

In the changelog however you can see that the game got two new uploads on release day, sadly there is no time stamp. The game got greenlit for release sometimes in the afternoon.
Would it have been possible to build the installer and test it from that moment on? Maybe, but it was further back in the pipeline (building, testing, release), other games got their installers first. It was just too late to get one before the GOG employees went home for the weekend.
I expect it to arrive today, or at latest tomorrow.

Edit: Linux and Windows offline installers are out now.

Regular user: "I think they have a day off because Saturday is a national holiday"
GOG employee: "Yes"

Aren't online shops exempt from the mandatory day off on Sundays and public holidays policy in Poland? What do your labor laws have to say about this?

How dare you bringing reason to a discussion on GOG!?
This your first day on the GOG forums?
You are supposed to sharpen the pitchforks and to light the torches.
Nothing else.
Leave your "reason" (blech) at home.

;)

QA and programmers do not sell, they produce. Technically they are just suppliers. Hover I have no idea if there's a legal exception in Poland.

In our case we produce, sell and support software, but only to customers who only work five days a week anyway. On Saturday and Sunday there's only a skeleton crew in support, mostly working in home office. All the others don't work on weekends.

Interesting!
My question, however, relates to a more general aspect: Is CDPR/GOG, as an online business, exempt?

If they are, there seems to be no good reason to make customers who prefer using the website library endure an additional waiting period. If they are not, that's unfortunate, but then they should communicate this, rather than risking alienating parts of their customers.

They actually wrote on the game page that installers are arriving "soon™".

Also a mod did answer in a thread and on discord that they gave two days off and that's more than we get from any other store.

Why would they communicate the work times of their programmers and similar divisions? That's none of our business, is it? I worked for a couple of companies over the years, most of them selling software digitally. In none of them QA worked on weekends. The store homepage works (well, for the most part anyway), downloading works, Galaxy works, games work. And for this game with the missing installer we got a message about the delay. What more do you expect?
If not for this one game, would you even have noticed that they had a day off if no one told you so?

Mac version is now available too.

A new build is incoming as well, with at least a small change which should assist some players solving a riddle.

It's hard not to notice when something goes wrong. The only thing I would normally expect from them is to inform their customers about their holiday schedule, including the dates they'll be on holiday and a news post telling us how long it will take to publish files, when they announce that they will be available soon. Instead, they posted 'Offline installers coming soon' some time during Friday, they managed to publish it for the client, and then there was no further communication on the forum.

Other companies routinely send out emails or post news on their website to inform their customers about holidays or weekends off, so customers are aware of potential delays or lack of support. This is a common practice that strengthens customer relations. I don't think that's too much to ask, and it's the absolute bottom line anyone can expect.
