One thing I've enjoyed about the releases by GOG has been their inclusion of virtual versions of the feelies and manuals that were included in the games original.

Going from memory, and this is stretching back a long time back to High School in 1993, there were some newspaper clippings included in the original box that fleshed out the story around Stauf's past, the manor, and the night of the Guests. I don't suppose theres any chance of these getting dug up and included at some point of the future? (Or if I'm going insane remembering them)

Here they are:

Since they are availabe on the Trilobyte web site I guess it would be no problem for GOG to include them in their release. Maybe I'm gonna write them a mail about it.
