Let me start with, I don't currently own Age of Rebellion, only Edge of the Empire.
I'm thinking of running a Star Wars game and the PC's will be Imperial Agents. They are being sent to a world where Rebels have been making attacks using Imperial weapons. It's believed that they are being supplied by someone in the Empire. The PC's job is to stop the Rebel cell, determine who is supplying the weapons and bring them to Imperial justice.
Do you think Age of Rebellion or Edge of the Empire would be the better system to use. I'm leaning towards AoR.
I'm also looking for suggestions or recommendations for sources I can look at to run this type of game. One part will be a mole hunt, looking for the Imperial traitor. I really want to get that right as most of our games tend to be hack and slash. I think a more "thinky" game would be fun.
