From the introduction:
In a Galaxy Nearby is about building stories and acting them out. Basically, it’s fan-fiction on two levels. The players get to re-tell the Star Wars saga just the way they want, and at the same time they tell the stories about their own characters and how those stories fit in with the main events.
There is no predetermined scene flow, except for the start and the end. The scenario is largely driven by what the players decide to do, with some help from the GM to set the stage for the scenes and push the story along, if needed.
