To me, this is just an assumption people have been making: that the Imperium is standards-driven and consistent. OTOH there are numerous references to the Imperium being a rather weak government that has difficulty enforcing its will.
Everything everyone has been saying since this post...
Despite valiant efforts of some to make it seem otherwise, we all really do know that the Third Imperium and the OTU actually is
only assumptions, right?
For 40 years different rules support different kinds of logic and assumptions for both implied and explicit setting.
That the setting materials contradict each other constantly.
That people read different things into different passages, cobble them together with other selected passages, and create in their own thoughts the way the Imperium really is. Even within the printed materials, there is no single Imperium.
And this doesn't even touch on what non-RPG materials a person has read. How one interprets the rules and setting materials will be influenced by what one has studied in life, experienced in life, and what one has
read (specifically science-fiction). All of these things will filter how read in the
Traveller texts and interpret them.
Things started getting wonky as early as 1980 for Classic
Traveller, when
Adventure 1: The Kinunir introduces a Battle Cruiser that is 1,200 tons (which makes sense using the tonnage range found in Book 2), and
Book 5: High Guard, which introduces rules for making ships that range up to a 1,000,000,000 tons. While there was no need to assume that huge ships would end up being part of the OTU, they quickly become part of it. Rending the Kinunir as a Battle Cruiser a thorn in the side of Hans and others who scrambled constantly to justify all the contradictions of a setting that was made up on the fly and piecemeal.
This is why there are constant arguments about how or why the Imperial nobility work one way or another. Or the way starports work (or don't work). And so on.
We are left with (at least in my view) choosing which materials and ideas we want to use, pointing at them clearly, and saying, "This is my setting, theses are the ideas I'm using."
This is how some of us can identify a period called Proto-
Traveller, which is distinct in nature from later versions of Traveller (and the setting that came attached to it). And how I can identify something that is even earlier than Proto-
Traveller (which I now identify as "original
Traveller") which lacks any concerns about the Third Imperium or the OTU, and looks at Books 1-3 as a springboard for making any number of settings at the Referee wishes.
We can point to any sentence or paragraph we want. But we're pulling form texts that were published across years, and then decades, often without coherence, and often with people with very different agendas for the kind of setting they thought the OTU
should be.
Example: I want an adventure-rich, dangerous, frontier, where traveling between the stars is exceptional and for a hardy breed. Hans explicitly said he wanted a setting where college students and tourists could casually travel from world to world without worry or concern. My model is Age of Sail, with empires in conflict, exploring and trading between Europe and India and around the globe. Hans' was 20th Century First World Europe.
What are the straport law levels like? What do you
want them to be like? They will be a reflection of your interests, your setting, and the logic behind it. Are they well regulated, clean, and calm? Or are they an romanticized-version of pirate dwelling Tortuga? Or do they vary between these extremes from world-to-world?
There is
no right answer. Even those of you who will bring in "logic" or "it has to make sense" into the discussion.
The books that inspired Marc Miller to create Traveller (The Van Rijn tales, the Dumarest Books, the Demon Prince books, among many others) don't make sense outside of their own logic. That is, they are self-consistent within their own logic, per story, and that's it. They are a colorful, exaggerated pulp science-fiction... which is a fine thing to be! And if one wants a setting the is more Hard SF, then go for it.
Certainly the
Traveller OUT has been taffy-pulled in several directions over the decades.
So, the only question is: What flavor of taffy do you want? What sort of texture? There really is no real "universe" out there. The material is inconsistent and contradictory. So, all that is left is for you to pick through the inspirations you love the most and make what you want to share with your friends.
