You can argue that this world’s main purpose is to distract us from the simple flight/pursuit/capture/rescue dynamic of the basic story action. But I’d argue that the final film benefits from fleshing the core action out in a way that situates it in a unique milieu. There’s also the point that worldmaking is no small achievement. Your task as a storyteller, George Lucas once noted, will change when you have to figure out what your character’s fork looks like.
