I ran BoFF as a teaser to give the group a taste of what Zeitgeist is like, especially with needing to think more than just going in with guns blazing (a reference that actually works in the Zeitgeist setting). It also gave us something to play while waiting for Chapter 1 to be released. I have not had a chance to read forward through the other chapters yet, but I trust my players to separate player and character knowledge. This is good since there are clues for 3 of the 6 NPCs there.
