If, like me, you are a fan and enjoyed that very game almost 11 years ago (this month!) then the following article may be of interest.
It's the very interesting story of the rise and fall of Trilobyte - the company behind 7th Guest. Most interesting to me were the pictures of the house Stauf's mansion was based on and the (only) shot of 7th Guest 3. I can only imagine what the third game would have been like!
I've recently gotten back in to the game (with the help of a newly purchased CD-i) and am enjoying the puzzles, awful acting and wonderfully upbeat music. They certainly don't make them like they used to!
