Like many here, I rarely ran or played a CT adventure "straight", that is right out of the box. I did, however, re-skin nearly all the adventures in various ways. Even more often, I re-purposed certain sections of various adventures.
For example, I re-skinned Death Station too many times to remember and I re-purposed the city-ship faction voting system from Nomads at least twice.
Of all the CT, the Doubles were the ones I was most likely to run or play straight. One of the earliest Traveller adventures I played in was Across the Bright Face and I died one hex from the starport! I ran a memorable Marooned session in which a new player fresh out of the Army immediately bought into the story, took over leadership of the group, and led them through an excellent game.
