In 1984, Game Designers' Workshop's original magazine Journal of the Travellers Aid Society (JTAS) ended with Issue 24, but there had already been an announcement in Issue 22 that a new and as yet unnamed magazine would replace it.
Also to maintain continuity, Challenge featured a separate section labeled "Journal of the Travellers' Aid Society", which covered Traveller exclusively; this special section lasted through Issue 28.
[1] In Issue 39 (1989), the magazine featured "The Hinterworlds," detailing of a sector in Imperium space for MegaTraveller; in subsequent issues, MegaTraveller articles were featured prominently.
In the January 1989 edition of Dragon (Issue #141), Jim Bambra called the magazine "an excellent source of adventures, ideas, and hardware for GDW's Twilight 2000, 2300 A.D., and MegaTraveller role-playing games, but many of its other features are also easily converted to other game systems.
"[3] In the October 1990 edition of Dragon (Issue #162), Allen Varney approved of the expanded vision of the magazine to cover all science-fiction games, not just those produced by GDW.
