Welcome aboard, CatKnight!
It sounds as if you don't have your original CT books. In that case, I recommend purchasing two FFE reprint volumes: "The Books" covering books 0-8 and "The Supplements". Those certainly contain everything you need and then some! The other volumes - the Alien modules, the games, the adventures and the JTAS reprints - contain many useful and terrific additions, but you don't absolutely
need them.
But if I had to pare it down to the absolute minimum, here's my Cr .02:
- Books 1-3. Obvious.
Available from QLI, the fine folks who host this site (click on the Classic Traveller link way up at the top of the page for their book 1-3 reprint volume).
- Book 4, Mercenary. The single most popular CT book outside the original 3, greatly expanding character generation for Army & Marine characters. Lots of nifty toys too.
- Book 5, High Guard. Expanded character generation for Naval characters, and new ship construction rules that also allow for truly big ships.
- Book 6, Scouts. Expanded chargen for the Scout service. Unfortunately, the expanded star system generation turned out to be flawed scientifically. The MegaTraveller-era "World Builder's Handbook" from DGP fixes the worst of these problems if you can find a copy, or the GURPS Traveller product "First In".
- Book 7, Merchant Prince. Expanded character generation for merchant characters, and some expanded trade rules if memory serves.
From the Supplements:
- Supplement 4, Citizens of the Imperium. 12 more careers including Belters, pirates, scientists and rogues, along with a bunch of pregenerated characters.
These comprise what I consider to be the core of the CT rules system. I must point out that the official Third Imperium setting, often called the 3I or "OTU" (Official Traveller Universe") began to creep into the rules, starting in a minimal sense in Book 4 but in varying amounts in books 5, 6 and 7.
From a straight rules-engine and generic play-aid standpoint, the next items would be:
- Supplement 2, Animal Encounters. Very handy when you've got your characters on-world.
- The rules from Azhanti High Lighting (available in the game of the same name, or the FFE "Games" reprint volume). An improved character-level combat system for Traveller.
- Supplement 6, 76 Patrons. A collection of adventure seeds sometimes now known as "76 Felonies" because many of the tasks involve break-ins, intrusions, smuggling and the like. Just remember that That's How It Was Done back in the '80s.
- Supplement 7, Traders & Gunboats. This one is iffy, but it includes some new ships you might find handy.
If you want to set a game in the Third Imperium setting, a few others will be needed:
- Supplement 3, The Spinward Marches. The frontier sector where Traveller was born and probably the single most popular part of the OTU.
- Supplement 10, The Solomani Rim. For a long time this was the only other sector on which we had official data. A highly-developed and more technologically advanced area.
- Supplemnts 8 and 11, Library Data (A-M and N-Z). Lots of useful information about the OTU.
Also highly recommended (regardless of whether you play in the OTU or not) is the set of miniatures rules, Striker. Striker also contains a vehicle construction system and a bunch of heavier weapons. Often available by itself on e-Bay and the like, or in the FFE "Games" reprint volume.
Unless you've got an easy source for all of these, though, I stand by my original statement - spring for the "Books" and "Supplements" reprint collections from FFE.
Nothing else in CT is really
neccesary. The JTAS reprints have a lot of great stuff in them, though, things like variants, explanations of technology, additional information about many of the alien races, adventure ideas, etc. I give these a slight nod over the Adventures and Short Adventures reprints, but those are full of nifty things as well (and some of the adventures are classic for a reason).
You might want to check out some of the threads in this forum and the "In My Traveller Universe" forum for many nifty house rules created by our fellow participants, particularly the ones with "CT+" or "Modern House Rules" in the title.
EDIT: Websites! At the very least check out Freelance Traveller (
www.freelancetraveller.com). There are many, many more with tons of useful and interesting stuff.
