When you play, you'll make several key judgment calls. Everyone contributes, but either the players or the GM gets final say for each:

• Which actions are reasonable as a solution to a problem? Can this person be swayed? Must we get out the tools and tinker with this old rusty lock, or could it also be quietly finessed? The players have final say.
• How dangerous and how effective is a given action in this circumstance? How risky is this? Can this person be swayed very little or a whole lot? The GM has final say.
• Which consequences are inflicted to manifest the dangers in a given circumstance? Does this fall from the roof break your leg? Do the constables merely become suspicious or do they already have you trapped? The GM has final say.
• Does this situation call for a dice roll, and which one? Is your character in position to make an action roll or must they first make a resistance roll to gain initiative? The GM has final say.
• Which events in the story match the experience triggers for character and crew advancement? Did you express your character's beliefs, drives, heritage, or background? You tell us. The players have final say.
