RPGaDay 2019
Our group was more apt to have a cliffhanger than actual suspense. We rarely finished a scenario in one session, regardless of how late into the night/early morning we’d play.
One that sticks out was FASA’s “A Doomsday like Any Other”, a sequel to “The Doomsday Machine”.
Upon trying the ‘Kirk maneuver’ (i.e. blow up a ship from the inside of the maw), the crew found that we failed, and the GM stopped the adventure at that point.
Cliffhanger.
Suspense would be not revealing the result until the next session.
