I really like the Orbit RPG. Granted, this pdf is not the full game and provides only career expansions. The full game is not available in pdf, but the hard copy can be purchased for $20, including domestic shipping, from the author's website. Think the ghost of Jack Kerouac writing a Gonzo sci-fi RPG in 1982 , and you'll have a pretty good idea of the "feel" of the Orbit setting. The system itself is percentile based and allows for some shifting of narrative control between GM and players.
