Commerce/Trade Rules

[TheGodPan]

Have their been any rules published about large scale trading and commerce in a fantasy world? My characters are high level and recently became rulers of a very small but mineral rich kingdom. I was kind of shocked when two of the characters started talking about their trading strategies, and wanted to know how much they would make in the rules.

If anyone has seen anything like this somewhere, give me an idea of where to look.

A Magical Medieval Society: Western Europe has rules that might work for what you're looking for. They're primarily manor-level, but could easily be adapted for larger scales.

Try Empire...Can't think of the company name, but they did Evil and Gods and a few other one-word titles as well.

I have Empire, Magical Mideivel Society, and Fields of Blood. Thus far, I'm heavily favoring Fields of Blood, although I'm definately mining the other two for things to add in to the mix.

for a link to Old One's d20 Economic System. As I remember, it even includes four levels of complexity, each building upon the previous, so you can choose one to fit your needs.

I don't think I've seen any trading system, but I have seen a system for building and running a merchant house or guild. It was in the Lands of Molokai source book, which I think is now different for 3.5. It's here: http://www.rpgnow.com/product_info.php?products_id=2335&

Is Old Soul Around?

I really liked Old Soul's economic system and I expanded on it a bit.


Is 'Old Soul' still on the board? I'd like to post it if he/she wants to GPL the original.

I can recommend the Old Soul file its managable and a great base.

Ran into the same problem recently, except I'm the player. The Mystara setting has some trade rules somewhere - I'd guess look at info about Darokin. Played around with those rules a bit ... they don't work that well for regular trade activity in my opinion.

In particular here's the sort of level of detail I want:
(a) buying prices in locations
(b) selling prices in locations
(c) costs of trading (hiring guards, mules, wagons), lodging in town, food for animals and guards
(d) duration between locations and time in town to trade
(e) market modifiers as you satisfy supply/increase demand, etc.

The Mystara system has (a), (b) and (d). (c) you can get from calculations using the 3.5E PHB prices. However, you then realise that the duration can be too small and the end result is profit per year can be too high.

I think my DM will end up fudging some numbers based on the Mystara rules.

Anyway, if anyone knows of trading systems with this sort of detail where profit doesn't end up being exponential long term, that would be great. (Old One's system is not too bad, but there's no direct account for how long it takes to get between (a) and (b).)

I believe there used to be a system in The Minrothrad Guilds. Although that was the old D&D Expert system....
