"Traveller is a roleplaying game (RPG).
  • It started its life as the shared science fiction universe of several college students in Illinois who later decided to publish a RPG.
  • It grew into so much more: RPG books, board games, novels, computer games, a universal sci-fi gaming system, world-building tools, etc.
  • In the end of ends, it's just a great, damn story!"
