rules. Traveller The original version was designed and published by GDW in 1977. The core rules originally came as a box set of three black digest-sized books, and were later compiled into a single volume rulebook. Supplemental booklets included advanced character generation, capital ship design, robots, and more. Eight boxed wargames were released as tie-in products. This edition is also sometimes called by the retronym Classic Traveller. MegaTraveller A new edition, published by GDW in 1987 and designed by Digest Group Publications. The game system used revised rules developed in DGP's Traveller's Digest periodical. The game was set during the rebellion which shattered the Imperium.

Wiseman and published in 1998, GURPS Traveller uses the third edition of the GURPS system and takes place in an alternate timeline in which no Rebellion occurred and Virus was never released. Steve Jackson Games produced numerous supplements for the line, including details for all of the major races, many of the minor races, interstellar trade, expanded world generation, the military forces of the Third Imperium, and starships. Traveller20 Published by QuickLink Interactive (QLI) in 2002, this version uses the d20 System as its base and is set at the time of the Solomani Rim War around Imperial year 990, about a century before the era depicted in the original game.
