Specifically, when players are buying and selling goods across worlds, do you levy a customs charge or tariff?
Unless I missed it in the rules, there doesn't seem to be any...which means how does the Imperium make money if not through import and export tariffs? (it isn't by direct taxation).
Thoughts?
There is a CT JTAS article that speaks to importing/exporting goods and local currency (not quite tax, but close).
To keep it simple, in my games, I just use a round number.
What I may do, though (as suggested by the article I cite above) is raise and lower standard prices on goods depending on where the PCs are.
And, if the story requires (or permits), I'll nag them will little things like the air tax mentioned in
The Traveller Adventure on Aramis.
I'll also look at long term miscellaneous expenses. I'll take the long term expenditure, based on their SOC (from
The Traveller Book), and I'll remove the number of days they character spent aboard ship (in jump and normal operations), and then charge the character that amount for the month.
I'll do this monthly in a campaign, representing all the little odds and ends, drinks, clothes, nic-knacks, stuff that a person will buy.
As we game, if it's a small expendature: "I'll buy the NPC a drink." I'll just say, "Don't worry about marking off the credits. We'll call it part of your monthly expenses."
OTOH, if the PC ends up making contact with the black market and purchasing some weapons and ammo, I won't count that against monthly expense. The PC will have to spend the credits.
