Haha, hey thanks guys.  Honestly, this is what high end customers want.  They already have a room (sometimes many rooms) filled with smaller puzzles.  As I understand those that collect, everyone wants a grandmaster piece for right in the middle of the room.  
What I didn’t share at the time is that they get to add some custom elelments to the design, help decide what kind of treasure to put inside AND there is a handwritten leather bound journal that sets the story and is filled with clues!
Who says you have to grow old?
