The game will start fairly late in the year 0 BBY by the official timescale. For those less versed in the universe, the year 0 BBY ends with the Battle of Yavin, in which the first Death Star was destroyed.
The party will be employees of a small shipping company based on Alderaan, which specializes in medium-value goods from the Outer Rim. Due to the potential danger of piracy in these sectors, the company has secured Imperial licenses for moderate personal and vehicle armaments. Because of the legal circumstances, all weapons will be provided by the company, and not personally owned. (In practice, this merely means that your characters will have a few extra credits, and there may be legal complications down the road. You'll be starting out with 4 stripped-down Y-Wings (removing the Torpedo lauchers, gunner's seat, and Ion turret, as the company did not see a significant need for such heavy weapons, and declined to by the prohibitively expensive liscence fee. The missing systems were converted into small cargo bays that count as smuggling compartments) and a medium sized, lightly armed freighter. I'll have a full set of NPCs that the PCs will replace in whatever role they decide to take. (For example, there will be 4 NPC fighter pilots created. If Lucius decides to roll a fighter pilot, there will be 3 NPC fighter pilots.)
Apart from that, I'm intending this to be fairly sandboxy. If the party wants to join up with the Alliance (or Empire), turn pirate, or simply set up a cargo run; that's what we'll do.
