Why is that? Is it because the material came from magazine articles? Or the material was not written by Marc Miller? I'm confused by the term "early CT" I guess.
Shonner,
First, canon
accreted, it was not centrally planned. It was a lot of people writing a lot of things over a lot time without much fact checking going on. GDW was interested in producing gaming materials and not in producing a completely internally consistent universe. Using a rough analogy, they weren't going to sweat over the threads on the screws in a closet door hinge when there was still an entire house to build.
Second, when
Traveller began in 1977, the term canon wasn't even used in the way we use it now. No one knew that RPG
settings would eventually out sell RPG
rules or that GMs and players would want heavily detailed settings with high levels of internal consistency. How we use RPG materials and what we need from RPG materials wasn't foreseen.
This means that a lot of stuff was written that didn't jibe with stuff that was written before. This also means that a some of the things that were written didn't exactly fit the setting either. Making things even screwier, there are things that were deliberately
overwritten too! So we end up with things in otherwise canonical books that contradict each other, things that have to be ignored, and things that no longer are true.
Han's mention of the Darrian's sun destabilizing is a good example of things that contradict each other. If you read all the passages in
CT and
MT that mention the date at which that event occurred, you'll end up with three (or four?) different years. Obviously, it didn't happen three (or four?) different times, so all those dates but one are wrong. Someone simply didn't check what had been written previously carefully enough.
The jump torpedoes in
A:4 Leviathan are a good example of things that don't fit the setting. Their existence contradicts the setting's assumptions regarding the minimum size of jump capable craft. GMs can come up with all sorts of explanations that allow them to keep jump torps in their personal
Traveller Universes but, as far as the
Official Traveller Universe is concerned, jump torps do not exist. Despite jump torps being in an otherwsie canonical book, they are ignored for the
OTU setting.
LBB:2's hull limitations for maneuver and jump drives is a good example of things that have been overwritten. When you use
LBB:2 starships built on certain hulls can only have so much thrust or jump so far because the drives you're allowed to use in them are limited. That lasted only two years from 1977 to 1979 when
High Guard came out and the hull limitations were overwritten. Again, GMs can still use those limits in their own
TUs but the limits to do not apply in the
OTU.
A lot of what sour, old, minutae obsessed, poops like myself talk about is just what published
Traveller bits fit into the canonical setting, just what bits do not fit the canonical setting, and just what plausible explanations we can craft to fit more bits into the canonical setting.
