throgh: Why buying on Steam? There is no difference either treated here as second-class customer or there dealing with unneeded DRM-system. For me then it is better letting this game pass!
trusteft: I have a feeling this is entirely GOG's fault. They do not have their #%$@ Galaxy client for Linux yet, and the publisher wants the client to work as DRM for the online component of the game. When/if GOG releases the client for Linux, the game might appear here too. Of course it will be interesting to see then if the game will REQUIRE the client for the Linux version, even for single player.
The day this happens is my last one here at GOG because then they have broken with everything they promised. DRM-free? Some kind of silly joke therefore. This game should have never been released here!
