I actually live in the same city where the original 7th Guest was created, Medford, Oregon. The original dev, Graham Devine of Trilobyte, invited me to visit them at their location on McAndrews back in 1996. I didn't know anything about them, I was working as a barista at Starbucks and he would come in for coffee and we would chat a bit. He was a very humble person. I had no idea how big of a guy he was until after Trilobyte shut down and he went to work for ID.

Another one of the developers, named Don (I think, or was it Paul?), told me of the secret cheat code for the original game. I cannot remember what it does, but I haven't found it documented ANYWHERE. If you get the original 7th Guest game, the password is "Don_R Zaphod_B". I can't remember what it does but you type it in when the game first boots up and then I think you hear a chime, if I recall correctly.
