Our group of 5 loved playing Museum Nocturnus. Everyone could participate as much (or as little) as they wanted. Since it was our first venture, we had a little trouble getting started, but things picked up quickly from there.
Took us 3.5 to 4 hours. An enjoyable afternoon with friends. Thanks, Eddie Smith, for introducing us to Deadbolt.
We were encouraged to pass the box along, but the "consumable" paper clue cannot be re-used. Perhaps, it could be available to re-print from the internet site?
