Ba dum tss!

Great to see it here!

There is just one problem...
This game had Linux port on steam on DAY ONE:
https://steamdb.info/depot/257513/manifests/
https://steamdb.info/depot/257511/manifests/

According to widely available data the Linux port was made by original team (example of data here https://www.pcgamingwiki.com/wiki/The_Talos_Principle).

So what EXACTLY would be the reason for missing Linux port on GOG "this time"?
Explain yourself GOG. We are all ears.

Ditto. Already own it on Steam. I really like this game, and would gladly buy it again to have it DRM free, but not until the Linux version is available.

Hope the Linux version is brought over.

why would gog bother with 4th class citizens linux users. no uses or cares about it.

Did you try asking Croteam about it? Epic store doesn't sell Linux versions, so I don't think they are relevant to this.

Because the Linux port was subsidized by Valve.

Im gonna buy it anyway because of the good launch regional price for Argentina.

Thanks, didn't know that. I had got the game on my wishlist on Steam. Now I'll rather drop my plan to try it.
This situation creates some serious moral dilemma for me - kind of function error ;) because I don't want to support DRM if the game is available here, but I also don't want to support Win-only releases if Linux port is available elsewhere...

Interesting. So, do they have some sort of exclusive on it? Hopefully, if so, it is time-limited? Is that information even public?

Why would Steam be pumping so many resources into Linux support, I wonder? Clearly, they are a bunch of idiots ...

/sarcasm

First time? /s

No, LITERALLY.

This is "THE" case for A LOT of games here.
You can either get game DRM-free on GOG but WINDOWS ONLY, OR you can get the original Linux port ON STEAM (which given Linux it means generally either "DRM-free except for files obtainment" or "can be made DRM-free by casual coding means", that's how it is in most cases [ unless it's Feral Interactive of course :P They throw pretty "Windows Defender memes"-esque gate in the way if you know what I mean ;) ]).
STEAM at least CARES about Linux...
So the dilema is actually pretty high if you care about both DRM-free and Linux...

I haven't heard of Valve forbidding any developers releasing games in other stores. Unless it's some kind of secret deal?

No, we are not gonna have it here.
Neither "THQ Nordic" (Desperados 3), nor "Team17" (Blasphemous) bothered to bring Linux versions here; GOG allows and tolerates this kind of behavior (they probably think "No Linux == less headache").
Plus, in the light of recent developments regarding "Serious Sam 4" I doubt Croteam has anyone left to cater to Linux folks (after Alen Ladavac has left them for Stadia).

I didn't realize that; they sell Mac versions though. The Talos Principle is also available on macgamestore.com, so there's clearly nothing Steam-exclusive about it.

On another subject, it's kind of too bad Sigils of Elohim isn't included and seems to be Steam-only. It's minor but still a nice little bonus.

YES!

But it's not like it requires a ton of work on something.
Especially since it's their own engine that they use in this game (so they should known very well how it works, there is no "we don't know Unity / insert-engine-name-here enough to deal with it promptly" excuse).

We have no achievements for Linux ports on GOG. Period. Same goes for overlay.
So essentially there is close to nothing to be required to be done to release Linux port of this game here except for working on GOG Cloud FOR LINUX support.
That's about it since controller support is handled by game engine itself (there are no "GOG wrappers" for it) afaik.
So, really, releasing this port here should bo no challange.
