Instead of the Industrial if Pop 9+ and Polluted, why not make economics part of the profile?
Here is what I have so far, criticisms, critiques very welcome (although I have no idea what I am going to do with this yet so suggestions there would be good too)
I concur with your criticisms. I am running a merchant campaign, and I fail to understand the rationale of some of the trade system adopted since the LBB Merchant Prince.
Why is there a modifier for the difference in tech levels between the sourceworld and marketworld? This was not in the original first edition LBB of Books 2&3. The tech modifier which exists in Merchant Prince, MT, and T4 would always mean there is more freight/cargo and passengers flowing from higher tech worlds to lower tech worlds.
I'm not an economist but observations tell me that there is plenty of cargo (usually raw or processed resources) going from lower tech levels to higher tech levels. Also, while many tourists travel back to nature (low tech) to get away from the city (high tech), there are some tourists who seek out high tech playgrounds (i.e. Las Vegas, NYC, Disney, MGM).
Other passengers might include refugees fleeing from war, oppressive governments and law levels. There are the jobless or impoverished traveling TO industrial or rich worlds. Then there is the business traveller who goes where the business takes him.
For the availability of cargo/frieght and cargos, I prefer the GURPS Traveller modifiers I find in Far Trader. Positive DMs for cargo along the following pairs of routes: In-Ni; Ag-Na; Ag-Va; Ag-De; Ag-Fl. Positive DMs for passengers traveling TO: Ri worlds, Cp worlds.
Any thoughts???
