TStael: I rather think CD Project Red should first deleniate business wise development (The Witcher) and distribution (gog.com). This bears nothing on stock-holder ownership.
My suspicion is that the money is on the distribution - not on game development.
There's money to be made in video game development, publishing and distribution. Otherwise if any one of those categories didn't have money in it there would be no company doing one of those things that are unprofitable.
I think it is important to note though that CD Projekt RED is just the game development studio and is not itself the parent company. CD Projekt is the parent company. Because the "CD Projekt" part of the name is shared between that and the studio people confuse them and use them interchangeably but it then gives the impression that GOG.com is a subsidiary of the game development studio which is not correct.
The CD Projekt Capital Group organizational structure has "CD Projekt S.A." at the top of the hierarchy with "GOG Ltd.", "GOG Poland Sp. z o.o.", "CD Projekt Brands S.A." and "CD Projekt Inc." underneath that (taken from their website). CD Project RED fits in underneath CD Projekt Inc." if I understand correctly from the materials available.
I point this out only because a lot of people seem to confuse things when discussing these sort of matters and I think it is important to clarify these things so people get a better understanding of the organization of the company if speaking about how it should be organized. If your statement is reworded to remove the "Red" out of it as follows:
"I rather think CD Projekt S.A. should first delineate business wise development (The Witcher - CD Projekt RED) and distribution (gog.com)" then it makes more sense, but then we also see that the two are already completely separate from each other because they are. The organizational chart that shows this is at:

In a nutshell the game studio does not run GOG.com, and GOG.com does not run the game studio. The parent company runs them both as separate entities already. Obviously they make money both from their video game development (CD Projekt RED) and also from video game distribution (GOG.com), and both are highly profitable. But with respect to their specific company (CD Projekt S.A.) as a whole, the money is in both video game development and distribution, however the majority of it is from video game development not distribution as you're suspecting. The reason I can say that with confidence though is that CD Projekt S.A. is a publicly traded company on the Warsaw stock exchange and thus has to disclose their financial statements. The financial statements publicly available on their website show that the majority of their profit comes not from GOG.com games distribution, but from the video game development studio from the Witcher game series.
No need to take my word for it however, the financial statements are here:

These details may or may not influence one's thoughts or ideas about what the company or any one of its subsidiaries should do or what might be good for business, but understanding the actual structure of the company is an important part of the speculative process I believe if the speculation is intended to be serious.
This is why I have said that it makes no sense for CD Projekt RED to acquire Interplay titles. I'd go as far as saying it would be highly unlikely, because their core goal is to do nothing but develop video games, and to do so one game at a time and do nothing else. Again, this is the game development studio part of the larger company we are talking about here.
"The company aims to follow the Rockstar Games model, where the company works on a single project with a large team, and avoids working on multiple projects at the same time." --
http://www.gamesindustry.biz/articles/2016-04-27-cd-projekt-games-will-follow-the-rockstar-model Acquiring another failed company's old video game titles has nothing to do with video game development, nor of pursing their goal to be a self managed game studio working on a single large project at a time, so unless they were to reassess that goal I speculate that it is not something going to happen.
However, if when someone says "CD Projekt RED" they actually mean "CD Projekt S.A." - the parent company, that is a different thing. They could create a new subsidiary called something else to speculatively invest in other failed video game company's non-profitable game products in order to keep the venture separate from their currently highly successful ones at the organizational structure level. But that doesn't have zero risk to it either and would IMHO. If someone thinks most of their money comes from game sales on GOG.com and forms an opinion that buying Interplay's titles would boost GOG.com sales and make them even more profitable, that's an ok opinion to have but it isn't backed by sound reliable financial data of the actual company that shows it is The Witcher game series developed by the game studio portion of the company that is actually the basis of the majority of their profitability (see the linked financial statements above).
Buying up the Interplay titles wouldn't be just distribution though, it would be maintenance, publishing and distribution, possibly with other publishers involved in other regions perhaps as well (as has been done with The Witcher games for example over time.) The "maintenance" portion of that is development, and that's something that sucks up resources. Judging from both GOG.com and CD Projekt RED's individual "Careers" pages that perpetually seem to list positions for developers, it is either suggestive that they're finding it hard to find the right people to hire, or that they're hiring people left and right in a continual basis and hiring more and more. That's hard to say, but there might possibly be information in the financial disclosure details concerning head counts on that perhaps. (I never investigated that).
Nobody can say with certainty either way whether they would or will do something like this, but based on a reasonably good understanding of their corporate structure from publicly available information, knowledge of the company's stated goals based also on publicly available information, it doesn't seem like buying up the Interplay catalogue en-masse would be something viable for them to do in any part of the overall parent company or its subsidiaries IMHO. They're doing well but they aren't moneybags like Ubisoft or EA either. If they could pick up a couple of titles for pennies on the dollar that need minimal maintenance and ongoing resource commitments presumably like the SSI Gold Box titles for example, that might make sense. But the idea of them doing something big beyond something like that with any of this, pursing mobile ports of the games etc. is seemingly way outside of what they do as a company right now, and outside of their area of expertise IMHO. I just can't see it happening.
For CD Projekt S.A., the way the numbers stand right now - the majority of money is all in video game development, and assuming Cyberpunk 2077 does well when it is finally released, that will become the largest portion of their incoming revenue at the time presumably, especially if the game is anywhere near as successful (or more) than The Witcher 3. Their core focus should remain on where the money is, and perfecting and improving those things. They're not Yamaha. :)
