EDIT: My query has been answered in the official forums, I can now buy this game!






It looks like gog users are getting shafted yet again by asshole developers... correct me if I'm wrong but the gog version doesn't seem to have the "second Sight Update" that has dropped for the steam version, I hope it's another case of truncated patch notes that is common here on gog, if not, then I'll have to bypass this title!
