I've noticed for some time that you do a real nice job on Steam-forums, asking about GOG-releases on many games :)
I would have done the same if I had an account there...and would probably have been banned pretty quick for begging every day at Euro Truck Simulator 2 and Snowrunner forums :D
I've been talking to various studios for a few years now to convince them. It's not always easy but I try to do my best to promote GoG.
I have a little more ease with French studios because I am French myself.
Lately we could see the game "Broken Piece". To have discussed with a person of the team last year. I'm happy to have been heard and that it was released on gog.
They are also happy to have the game on gog. :)
I try to do my part regarding swedish studios, lurking the steam forums and asking the question whenever something looks interesting. I've basically stopped buying PC games outside of GOG since about 2 years ago.
