But yes, I have been in direct contact with a publisher (who also has their own storefront) after GOG support, expectedly (based on prior experience), refused to support me on the grounds that they do not .. support .. my system (even though I pointed out the issue was not system specific). The publisher had no issues supporting me, and indeed they were comparatively quick to respond and easier to deal with than GOG.
Here's how it goes with GOG:
* Have a problem with your game? Sorry, we don't support your system (and we also release buggy games that would be easy to fix but that's the users' responsibility).
* Want refund? Sorry, refunds are for technical issues only and "we do not support your system" is not a technical issue.
* Want your forum posts deleted? Sorry, we can't do that because we'd have to delete your account and besides, it'd break threading (nevermind that moderators are already breaking threading and removing posts without deleting accounts; and threading breaks only because their software is so crap).
I haven't got a single success story to share about GOG's support. And up til now, the lack of refunds has become a major pain point because you're not entitled to either support or refunds if you can't get your game working on a system GOG does not want to support.
This got worse when Judas' wine thread become a ghost town after the Linko90 fiasco, where GOG decided to side with social media outrage mob and fire their own people and presumably make a policy change that disallows their employees (who in the past had given unofficial but first class support on forums) from being active members of the community. Around the same time linuxvangog started looking for a new job; I believe GOG either fired him or pissed him off enough to have him look for a better place.
GOG really doesn't care about Linux, which really sucks, because a lot of Linux users do care about DRM-free games.
But hey, I've been enjoying STALKER lately thanks to you & GOG.
