Over the years I've accumulated several displacement tons of house rules and setting changes for Traveller. They lie scattered in various computer files, notebooks, and margin annotations, and I decided to start a thread where I could actually collect them in one place along with commentary on my rationale, and maybe get a little feedback from other Traveller gamers along the way.

Traveller is one of the most extensively supported roleplaying games ever, with numerous editions, supplements, board games, out-of-print apocrypha, fanzines and an active intreweb fanbase which produced at least as much new material as the official publishers themselves. It's a hot mess, particularly the original, 'classic' Traveller, which remains my favorite edition of the game. It's the one roleplaying game for which I have boxes and boxes of published material and folders full of pdfs. I am not a true completist, though I believe I have most of the materials published for original Traveller and a fair amount for MegaTraveller as well. I'm also going to use this thread to catalog the stuff I actually use in-game.
