Hey, I wrote that Jack Vance article, and I'd forgotten all about it. Shows what time and age can do to a once promising mind. If you're a fan of Vance's Tschai series, then that issue (#40) is worth any price.
A quick skim through my issue collection turns up --
#17: A couple of articles on Imperium
#18: Laser pistols and variable swords
#20: Psionics variant
#24: Review of Mercenary
#27: Review of Snapshot
#32: Special Traveller issue covering aliens and pseudo-human characters, Ithilien class scout ships, and a bunch of reviews, including Azhanti High Lightning
#35: More psionic abilities, and my winning entries in the "Characters I Wouldn't Let In My Universe" contest
#36: Traveller fiction and an ancients artifact, the fire web
#37: "The Alien" in Traveller terms
#38: Buying used ships
#39: Rumor reliability by yours truly
#40: Special Traveller issue, featuring an essay about Leviathan by Marc Miller, a space combat variant by me, and the fabled Tschai: Planet of Adventure supplement
#41: Triplanetary review
#43: more aliens plus a major expanded combat variant featuring lots of situational die modifiers
#44: An entire set of rules for AFV design and combat rules by William Barton, a regular Traveller contributor. IMO, these are far more playable than and generally superior to Striker.
#46: Special Traveller issue covering terrorists, lots of reviews including Fifth Frontier War, and an adventure by the Keith brothers, Flare Star.
#47: Physicians
#48: Storm, the adventure sequel to Flare Star, by the Keiths
#49: Equipment for terrorists and an interesting essay on science fact vs. science fantasy by Greg Costikyan
#50: Periastron, #3 in the Keiths' adventure series
#52: Spy cars
#53: Conclusion of the Keiths' adventure series and a featured review of Striker
#56: The splat gun, plus a campaign world for Space Opera (not Traveller but easily usable)
#59: review of The Traveller Book
#60: Featured review of Star Frontiers (again, not Traveller, but as the game's editor, I decided to tout it anyway)
#62: Chainsaw combat (really)
#67: Interdiction Station adventure
#72: reviews of Gamelords supplements
#85: 200-ton starship (Starjammer), Megatraveller adventure (Corsair Contention)
And there my collection peters out. That turned out to be more comprehensive than I intended, but looking through those old issues was great fun. In its heyday, TSG was the best gaming magazine out there, IMHO.
