I run “The Great All Hallows' Eve Procession” yesterday at the SagaCon in Osnabrück. What a pleasure! While players don’t have much choice where to go, since they are part of a procession, there is are plenty of things to do and see. The random elements make the adventure fun to run, while the clear structure offers support for the GM. I highly recommend this piece for one or few shots. Bonus: the structure of the adventure makes it very easy to fit the game into a predefined time slot.
