finkleroy: All the content from the 10-in-12 DLC drops is in the offline installer. It's been confirmed that it contains DRM that requires an internet connection to unlock the content. GOG support confirmed this but refuses to remove the DRM. So much for their DRM-free mission statement. This isn't even a multiplayer issue; it's DRM for singleplayer, and that's completely unacceptable.
So what would happen if AFTER the unlocking you disconnect from the internet? Will you still have the content unlocked? If so, then I would not really consider this to be DRM since in this case you could store those missing files somewhere and add them back for the next install manually.
