This is a piece of nostalgia worth buying. if you played Traveller in the original boxed set (ol`grognard edition), you will have probably perused a least one JTAS and enjoyed at least one article or adventure from it. It is a prodigious resource for GMs & players both old & new.
Some of the articles require revising depending on your version being played (I`m using the Mongoose Traveller edition in my campaign) and some articles are outdated or have been surpassed by more modern rule sets (Remember: Traveller has been in one iteration or another since 1977!).
None the less, it still has a cornucopia of adventures, articles, primers, devices, equipment, weapons, ship classes, deck plans, variant rules & more for anyone who plays or GMs this game.
For example, JTAS #1 contains the classic adventure "Ànnic Nova" which has been reprinted as an official Traveller double adventure 1 (which are hard to find). Each subsequent issue of JTAS has a least one adventure (full or seed) to wet the appetite of any GM.
As well, there are new ships or variants to use. A player wanted a more distinct looking scout courier, so I used the Serpent class scout courier (complete with deck plans from JTAS 2.)
All in all, it worth a look at. If anything, it can serve as inspiration for GMs of this RPG.
