Wrong wrong wrong.
The problem with Traveller is that nothing's ever been fixed-- they just kept making new versions.
At some point the line needed someone to clean things up and settle things-- sorta like SFB's "Doomsday" edition. (Even Car Wars underwent several stages of iterative improvement.) With Traveller the idea was always to come up with new variations without fixing anything that had gone before. This sucks.
Marc and Loren are probably rolling their eyes at this one. CT *was* fixed in several sub-systems long before MT came along. There were two or three fairly distinct "editions" within CT even without looking at the combat variations provided by Snapshot, AHL, and Striker, not to mention two versions of High Guard. The first few printings of B1-3 were different from the middle years, and different again from the Traveller Book and the Ultimate Edition box. CT as GDW wanted to print it and play it was a done deal in 1984.
The "problem" is that these CT-internal editions all blend together for all but the oldest of players who were around to watch them happen, and many don't even realize that they were already on "2nd Edition" by the time High Guard existed. Here's a clue: if your B1-3 tell you that the Type C has Modular Cutters, you're already at least on 2nd Edition.
Some of the items mentioned here already are non-trivial. Changes to those systems threaten to make the game "not-Traveller". Other items mentioned have already been changed, but under later editions of the game. "But that's not CT!" I hear. No, it isn't, but it IS Traveller. You play Traveller, right? As CT fans, you already need a Geek Code to decipher your particular sub-flavors. What is the resistance to looking at the later versions to see if your particular issue has been resolved?
"But I hated MT!" No, you hated the Rebellion and the errata, and missed the task language, WBH, and some kickin aliens books.
"But I hated TNE!" No, you hated Virus, d20s and no TL15, and thus missed Ship Shares, corrected stellar type distributions, common-sense power usage, super-missiles, and external docking clamps.
"But I hated T4!" No... Okay, that one I might give you, but you still missed out on SSDS, one or two useful new aliens (out of a dozen, granted), and a sexy book full of ironmongery.
"But I hated G:T!" No, you hated point build characters, hex grids, and only four stats, and missed starport design, rigorous treatment of many background institutions, and fuzzy world building.
"But I hated T20!" No, you still hated d20s (but capitalized this time) and an arcanely described character history system, and missed a new approach to starship Bridge volumes and another go at tactical skirmish combat.
I don't yet know what's to hate or miss about Traveller Hero, T5, or MongTrav, but I do know that the later-edition blindspot of CT and MT fans will only get bigger unless those who possess it learn to recognize it and look around it.
Why is it on you? Let's be frank. Any fixes that occur from here on will not bear the CT stamp. They'll be under TH, T5, or Mongoose logos. You're either going to have to graft stuff into your CT games, or continue to be unhappy.
