You all just wrote whole books defining the FFW and yet not once in any of those books did you give as rules for how things work or why things are happening. Jump Drives are rated by how many parsecs that they can travel. M-Drives are rated by how many Gs of acceleration they can put out. The Third Imperium uses the Imperial Credit. Every time you write a book, you define something. Traveller is not a setting, it is a system. If you have no wish to say, "This is how it works in Charted Space", then stay out of Charted Space. Every setting book says how it works within that setting, otherwise it is not a setting book. Why did you publish a Third Imperium book if you didn't want to define anything? Or Clans of the Aslan? Or Imperial Navy? Who founded the 3rd Imperium? What is a Major Race? What does the word Zhodani refer to? Defining things within a game world is literally what you people do for a business.
To quote an old designer at GW, what you leave out is just as important as what you put in. Put another way, defining a Major Race does not mean we should ever attempt to classify every Minor Race. I didn't say we should not define
anything, merely that we absolutely not try to define
everything.
That is a big difference.
How much does Refined Fuel cost? How about unrefined fuel? How about the cost of a Low, Middle, or High Passage ticket? These are the same across all of Charted Space, with some minor changes if the Referee feels like it, but that is not in the rules. Price of a Free Trader fresh off of the assembly line? Same price from one end of Charted Space to the other. So, you are being disingenuous by saying prices that are Charted Space-wife cannot exist, when clearly they already do in most things. Base Spec Trade prices exist everywhere also.
Think this through for a moment. What would the alternative be?
That Free Trader price almost certainly is
not universal. It is instead a convenience, a short hand if you will, that gets us 'close enough' without having to bog players and Referees down in the minutiae of starship pricing across Charted Space.
And here is the problem - if we
did want to get into those particular weeds, think of the page count to take all those variables into account, all the extra work it puts on the Referee to enact them, and how much the players are simply not interested because they just want to buy their new ship and start adventuring.
There absolutely are Traveller fans out there who want to see this stuff - and we can likely count them on two hands. This is something we often have to push back on with writers who sometimes have a tendency to create a simulation when they are, in fact, writing for a
game.
At the end of the day, this is what it comes down to. Traveller has to be a game that is played by many, many different groups. So,. a Free Trader costs MCr46.242. The Referee can plonk around with that figure if there are obvious circumstances that crop up during his campaign, but otherwise the primary function here is for players to know how much a Free Trader costs, buy it, and then get on with that night's session.
We can add to that, but we have to be so careful not to bog the game down, and the Core Rulebook is certainly not the place to do it.
To paraphrase a very wise Vulcan, rules are the beginning of wisdom, not the end.
