s23021536: What possible conceivable reason could a publisher have to not want to publish on GOG? I'm asking this question, based on all the awesome games I want to see on this site. I apologize if this was addressed on the Twitch thing, but my internet was simply to slow :P

Are the communication lines with the relevant people difficult / inefficient / awkward?
Can the process easily deadlock in bureaucratic mumbo jumbo?
Are the powers-to-be concerned concerned about their names next to games that might have significant compatibility issues on modern systems?
Do they underestimate sales figures and reason that it is not worth the effort?

Edit : Ok, perhaps I should add:

They're opposed to gog's drm-free policy?
They're greedy?

Niggles: Piracy with a P. They are scared of people downloading copies of a game instead of buying, and in doing so the publishers miss out on $$$. That's probably the main reason imho.

skynet464: Well with games like EU4 its a hell of a lot easier just to integrate the game into steam than to make multiple versions of the same game for different sites.

tinyE: I remember (and I can't prove) monitoring review sites the night Diablo 3 came out and hearing that cracks were showing up within an hour of release. Again I can't prove that but it made me laugh at the time.

Immoli: ...
Lets not make excuses, they WANT Steam.

lugum: not to mention when you try something their they are forcing you to install some dubious software.

cjrgreen: All of the above. Especially the problems with communication and championing in conglomerates. Nothing happens in these companies unless somebody sticks his neck out to make it happen. The usual consequence of sticking your neck out is somebody comes along with an axe. So it doesn't happen.

And not just compatibility issues, but also other issues involving the license holder's reputation. They may not want a game in circulation because it is not consistent (too retro, too buggy, can't support, doesn't mesh with current titles, too inexpensive) with the image they want to project. Whether we amateurs think so or not, the image and reputation projected by a publisher are extremely important and mean large numbers of dollars or euros or pounds or złotys to them.

Piracy is sometimes a reason but not the main reason. The main reason is the publisher is risk-averse to bad reputation resulting from problems with a retro title or their perceived assocation with a dealer in remaindered games.
