"Stock your starship, grab your gun, and take to the stars… fortunes don’t come easy!"
Setting: Humanity has gone to the stars and found them crowded with other forms of life and other sentient races, and science and technology have advanced vastly over the present day – but the essential nature of humanity is unchanged, just spread out over the sea of stars. An Imperium unites thousands of diverse and independent star systems under a single rule, but it is beset by enemies both internal and external. The Imperium is strong enough to defend itself from its neighbors, but has little else to enforce order within its territory. Order is the responsibility of local leaders, of which many ` bicker and feud, leaving a feeling of a wild frontier throughout the Imperium. Despite this civilizations on a myriad of worlds endure, and despite piracy, trade continues to flourish. Megacorporations and feudal lords conduct the bulk of this trade, but there will always be a place for the free trader – hardy travellers and adventurers on the fringes of known space, dealing in strange goods and smuggled cargoes, doing whatever they can to make a buck.
Characters: Think Firefly. The PCs form the crew of a free trader merchant vessel, wheeling and dealing with locals, while taking whatever cargos they can get to keep their spacecraft aloft and in one piece.
Game System: Traveller, GURPS, or Unisystem
