And, after completing their turn, they must wait for two or more consecutive turns to be completed by other players before starting another round of their own. During this time, they can't get busted, wasted, or fail at any stage, lest their progress get wiped and their turn invalidated. Players can play for up to three hours at a time, for example, wherein they can complete one story or payphone mission, and as many side missions as they like against the clock. Rules are simple but thorough, to ensure fairness and maintain structure.
