I had originally decided to run a d20 Modern game with this idea, but instead I'm going to run it Star Wars. It takes place on Coruscant, and the PCs are introduced to the crime underworld there. They are assigned such mission duties as assassinations, ship stealing, blackmailing, laundering, prostitution, spice dealing, etc. I have a few adventure ideas in my head already, but I was wondering if anyone had any suggestions?
