CT had pretty much integrated the OTU as a given by the time MT came on the scene, so it never struck me as a big change. Also, the later LBBs had become progressively more crunchy, so MT just looked like more of the same. It's only lately with all the evaluation of "proto-
Traveller" and the 1977 LBBs that it hit home that the OTU hadn't always been baked in.
Back way before the internet we tended to view editions as natural evolution, adding to earlier editions but not rendering them obsolete. In almost every case we tended to add more and more of our favourite bits from the new game to the old game, until eventually the balance flipped and we were playing the new game with some elements of the old one. Not just
Traveller, but also
RuneQuest,
GURPS,
D&D - anything we played that had multiple editions.
Ah, those halcyon days before we'd even heard of edition wars ...
EDIT: Oh, yeah, the original question - I think CT
could do with an update - not the same as "needs". I'd like to see more art, er ... I can't really think of much else. I like the retrotech feel of the game, and while I have firm favourites I think the many options in character generation, ship design, space combat, etc. just widen the appeal to different gamers, so I'd leave all of them in. But, as mentioned above, there are several
Cepheus Engine games that attempt to do just that (though most have their own setting conceits so they're not "pure" CT updated).
