Awesome!
Bought two copies from Runic a few years back to see if it was worth putting into our LAN game rotation. My game LAN is isolated from the internet, largely so I don't need antivirus, malware, etc. Both the hassle and the overhead. Then I found out about needing the on-line connection.
Runic offered some non-internet install they allow to military personnel; basically install some pre-installer, do the install, send them some file, get back another file from them, do something with it, send them back something, they send another thingie. Or something like that.
I sent them a message to the effect of, "Don't bother. If you ever decide not to treat your paying customers like thieves, let me know. I'll buy several more copies." I never heard back.
Thanks. GOG! You guys rock!
Oh, obviously, I bought it within a few seconds of seeing it on the main page.
