I am also bemused by complaints against Mongoose Mercenary. Neither Military experience nor background are essential for writing a roleplaying game, even a supplement aimed at combat. I do not recall games like Battletech being written by people with extensive military knowledge for example.
Classic Traveller may have been aimed at (or adopted by) ex-military people but Mongoose Traveller is not, and I would guess that the vast majority of people who enjoy the latter simply do not care at all about military minutiae.

I almost felt the same way as Andrew about FFW as I couldn't keep the board and counters in position long enough to complete a game or keep the players interested for long enough.
FFW....could never find players willing to spend the time to play the whole thing through. Sold it to a comic store after holding out for about 5-6 years in vain.
Gamer span of attention just isn't what it used to be back in the early days. Or maybe it was just overkill - Imperium was just about right timewise, but FFW seemed to scare away opponents.
A close second worst would be AHL - Never used it, never even punched the counters.
My biggest waste:JG's Starship Deckplans.I cannot stand them.They make the FASA deckplans look like works of the great renaissance masters.Really the only JG product I liked was The Darthon Queen.1st Traveller game I ever played in.I've run it a half dozen times over the years for different groups.
The 1st time the gm used all 3 plots(the terrorist strike,the mutany,& the monster) at the same time.Still remember my friend Brent finding the last bomb hidden in an upper deck fresher;as he reached in to disarm it it went off.Everytime Traveller comes up we start talking about that game & Brent still mutters about "dieing in the shitter".
Originally I was going to call this topic what was the worst Traveller book or supplement but then got to thinking about how much money I forked out over the years on Traveller gear and how some I wish I never bought (except for the completeness factor). My own copy of Azhanti High Lightning was played no more than 5 or 6 times (though I really only wanted it for supplement 5). So anything Traveller, by any publisher or manufacturer.
My own nominations are
1. Fighting Ships of the Shattered Imperium (what a waste of trees and my time)
2. Tarsus (would have been better as a bound book but no I kept losing bits)
3. Supplement 12 Forms & Charts (why?)
4. Games Workshop 15mm Traveller minaitures blister packs (I should have gone for the Grenadier 25mm ones)
