F.A.Q.:
1. What are "DFMRs"?
It´s a term which should describe that user efford lead to the addition of a game to GOG-Catalog via "forum-work".
2. What´s the idea of this thread?
This thread should link to all forum discussions with various publishers to get their games on GOG so folks who like writing in forums to push DRM-free gaming can support them!
Please don´t think you should only convince publishers that aren´t already on GOG, do also encourage particially inactive publishers to get their games on GOG!
3. What information do I have to mention?
Not much; mainly just paste the link and write in brackets which publisher,a short overview of game catalog and the language used in that forum!
Example:
http://forums.eu.square-enix.com/showthread.php?t=11760 (Square Enix | DeusExHR, Hitman4&5, FinalFantasy,...| English)
4. Will you sort those information?
Yes, but I cannot guarantee to be always in time...
...but I´ll do my best!
5. What´s about sub-forums? (New!)
Will only link to threads that already exist---it´s not important whether they exist for five years or for one hour; but I definitivly not will link to a subforum WITHOUT a existing thread dealing with the topic!

Gathered this link from the wishlist entry of HomeworldSeries:

http://forums.gearboxsoftware.com/showthread.php?t=273144 (Gerarbox| HomeworldSeries|English)

It´s good to see that others are creating such threads in publishers/ developers forums as well!

I really, really hope GOG can get the Homeworld series! The wishlist alone has over 17,000 votes!

We are asked to support their efford; it worked completly well for getting Risen and Risen II on board (DeepSilver didn´t even considered making GOG an option before "we"´ve opened up a thread in their forums...) and it might work as well for other games. That´s the core idea of this whole thread!

BTW: Saw this thread in the GOGforums (http://www.gog.com/forum/general/bethesdaidzenimax_contact_thread/page1) and it mentions this thread @Bethesda. Will add that too:
http://forums.bethsoft.com/topic/1502630-please-bring-the-fallout-games-bethesdid-games-to-gogcom/ (Bethesda|Fallout-specific thread| english)

Wow! Since both Risens have made it to GOG, I hope the Homeworld series will have the same chance!

What is with publishers that don't have an official forum, like Supergiant Games ("Bastion" and "Transistor") for example?
I tweeted them and they also have a facebook page so maybe we could make ourselves heard that way?
https://twitter.com/SupergiantGames
https://www.facebook.com/supergiantgames

Not sure about whether I should add it to the list or not...
...would proberbly grow way too big then, espacially if I´d start to collect mail connections;)

BTW:
Is there allready a "bring more of your old games on GOG.com!!!"-thread in EA, Activision or Ubi-Forums?
As they weren´t as active as they should have been in the last time it could be intelligent to open one...

Thanks for the thread! I'll dump what info I can, and you can decide if you find it useful or not.

Regarding SuperGiant, I was in contact with Greg Kasavin, and he said, "We have no immediate plans for this though we haven't ruled anything out for the future and appreciate your interest. For what it's worth the Steam version of Transistor is DRM-free and can be played offline once downloaded."

Somebody could start a thread here encouraging 2K to bring the X-COM games - http://forums.2k.com/

Thanks for that; added this piece of information!
