PixelBoy: It's not necessarily so that those indie developers are abandoning GOG, in many cases it has been GOG who rejected them.
There used to be a long period when almost every indie game I was interested in made an attempt to be on GOG, but they got every time the very same refusal message.
And at least one indie developer who has a game on GOG told before that GOG didn't accept any of the following games, including direct sequels to the one already here.
So it makes you wonder how often it is the store and how often the developers who choose not to co-operate.
THIS is my biggest gripe. Some may disagree, but I have ALWAYS disliked GOG's curation and have always wanted it gone. I'm here for DRM-Free games with offline installers, nothing else. There are very few DRM-Free stores out there and so they should not be acting as gatekeepers. It's hard enough to convince studios to go DRM-Free, so when they are willing, having some random GOG employee subjectively reject willing studios is not the way to go.
Some will say that I will open the flood gates, and maybe I will, but I'd rather sort through crap to find gems, than have a bunch of gems filtered out through an aggressive trash collection filter. If someone wants random subjective recommendations, they can look at
GOG's affiliate program. That's all curation should be though. A bunch of recommendations, NOT a hard block. Perhaps GOG could expand and promote the affiliate program more, but the curation has to go. Allowing AO games was a good first step.
Some will always complain, but at the end of the day, no one is forced to buy anything they don't like.
toma85: The Epic Games Store happened. This is one of the results. You can read or hear that developers starting to have problems to deal with several versions they have to release with each store. Steam and EGS are two versions. With GOG they have three versions. This is already too much for smaller studios. You also have developers here which removed games on GOG because of low sales. In this case they don't want to do the extra work for a GOG version anymore, e.g. CHANGE: A Homeless Survival.
I would always push such developers to release their games on GOG once they've stopped patching them. They're ready to abandon the game? Now's the time to release it on GOG then. GOG gets a finished and patched product, developers don't have to re-compile offline installers, or make patches.
