My upcomming game will have Nar Shaddaa and Tatooine as centerpieces.
I will start the players off in their ship, in hyperspace. They can decide if they are on their way from Tatooine to the Smuggler Moon or the other way around and what they are smuggling.
If they are flying from Nar Shaddaa to Tatooine, no problem, they can choose to smuggle anything; blasters, cyborg-prosthetics, slaves, spice, vibroblades... Whatever!
I guess all kinds of things can go through Mos Eisley, but what is likely to be smuggled out of Tatooine to the Moon? a tranquilized Rancor?.. It says illegal goods under major exports, but what?
