Suspense is not something I’m good at deliberately generating in my games. I’m sure there are instances where suspense has occurred in one of my games, but we keep things light-hearted enough that being deliberately suspenseful in a sustained way would be really jarring.
Of course, there’s always the suspense when success or failure comes down to one critical die roll. The kind of roll where everyone cheers when the player is successful or they collectively groan (or swear) when the player’s dice fail. Those moments make gaming memories.
