Story Points

If you prefer, you can give players a number of Story Points at the start of each session (typically 2 or 3). They can expend these to determine what happens next in the story. Having a currency like this means you stay in the captain's chair while allowing other players to interject when it's important to them. For most groups, a Story Point should allow the player to suggest a plot twist that can be resolved quickly or to establish a relevant fact or NPC, attitude. It can't determine the outcome of an entire scene or vastly alter the reality of the setting.
