GURPS Traveller

GURPS Traveller is a set of table-top role-playing game books by Steve Jackson Games, designed to allow game play in the Third Imperium science-fiction setting from the original "Traveller" using the "GURPS" rule system. Loren Wiseman (formerly of Game Designers' Workshop) wrote the core book for "GURPS Traveller" and served as line editor.
History.
Steve Jackson had been a long-time fan of "Traveller", and had previously talked to Digest Group Publications about doing a "GURPS Traveller" back in the late 1980s. Following the dissolution of GDW in 1996, Jackson licensed the "Traveller" property from Marc Miller, while Miller simultaneously licensed "Traveller" to Imperium Games. Jackson brought on Loren Wiseman to produce the new game, which was set in an alternate history of the classic "Traveller" timeline (which was at the time licensed to Imperium Games). Following its publication, "GURPS Traveller" was extensively supported with numerous background books through 2003, and the "Journal of the Travellers Aid Society" was resurrected as a "Pyramid"-like online magazine in 2000.
The game uses the GURPS (Third Edition) system and takes place in an alternate timeline in which no Rebellion occurred and the Virus was never released. Steve Jackson Games has produced over 30 high-quality 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. The game is often referred to as "GT". Loren Wiseman who worked with Game Designers' Workshop in the design and development of Traveller was the GURPS Traveller line manager and editor of the online magazine Journal of the Travellers Aid Society.
In August 2007, Mongoose Publishing announced changes in Traveller license and a strongly supported reintroduction of the Traveller system: Steve Jackson Games licence for the Journal of the Travellers Aid Society runs until the end of 2011. The distribution of "GURPS Traveller" products by Steve Jackson Games finally ceased at the end of 2015.
Difference between "Classic Traveller" and "GURPS Traveller".
Loren Wiseman and Jon Zeigler have attempted to keep the information, equipment, characters, style, and atmosphere of "GURPS Traveller" as close as possible to the original "Classic Traveller" universe. However, the use of the GURPS rules means there are several differences between playing "GURPS Traveller" as opposed to the original "Classic Traveller".
Current Edition.
The core GURPS ruleset was updated to a streamlined version with the August 2004 release of its Fourth Edition. In February, 2006, Steve Jackson Games released "". This book includes updated versions of the most essential mechanics found in the third edition books, including system generation, starship construction, starship combat, and interstellar trade.
The book also presents a new setting. Prior books in the "GURPS Traveller" line were set in an alternate timeline of the Third Imperium where the Rebellion did not take place - around the year 1120 (since the founding of the Imperium). "GURPS Traveller: Interstellar Wars" is set almost 2500 years prior to the founding of the Third Imperium, with a default year of A.D. 2170. The humans from Earth finally invent a faster-than-light drive for their space ships. They soon make first-contact with extraterrestrial aliens, and those aliens are human. The Interstellar Wars was intended as a much more dynamic campaign setting than the essentially static background of the Third Imperium offered in previous "GURPS Traveller" publications.
