And GOG refuses to add GNU/Linux support. Considering that many GOG games run in DOSEmu anyway and some come with native Linux support this is not really understandable.
Yes, that's one of their downsides. Even their reasoning is becoming less and less sensible. They claimed they still can't figure out how to offer long term support on Linux. May be Docker can help them.
GOG's position is totally understandable.
FatELF would of addressed at least some of these problems, but was largely rejected by the larger community of people not shipping proprietary products on Linux: https://icculus.org/fatelf/
Ping me at solomon@docker.com about this anytime.
