INTER-CASTLE Economy Suggestion
Good night,
I would like suggest you something that I think important, a INTER-CASTLE Economy (You maybe already thought about it, and if you didn't already added it that is surely for a good reason).
We just have to add 8 new objects what just have only one utility : for trade.
And why not two new classes : "Trader" (5in trade capacity) ; "Merchant" (3 in trade capacity)
_Velvet (7.000 dinars) (requires 5 in trade)
_Dye (5.000 dinars) (requires 5 in trade)
_Wine (2.500 dinars) (requires 3 in trade)
_Ales (2.5000 dinars) (requires 3 in trade)
_Linen (1.500 dinars) (requires 2 in trade)
_Leather (1.500 dinars) (requires 2 in trade)
_Flex bundle (1.000 dinars) (requires 1 in trade)
_Food box (1.000 dinars) (requires 1 in trade)
Enginer/Doctor/Sailor - who are supposed be more in trade context than others, should have 2 in Trade Capacity, than all others classes are supposed have 1 in trade - Serfs are not "intelligent" maybe they should have 0 in Trade Capacity -in middle age they worked for someone who sell their productions, not by themselves.
Traders Trains from Town, Merchants train from Castles.
People who doesn't have the Trade capacity required should have the opportunity to sell it in stolen goods (by exporting), that the price improve by the Looting capacity.
For create this news objects, you can take the .brf from Native (they exist in 3D -if I remember well- in it), that is free - there is no limit on this way.
What for ?
PW Versions before PWv.4 was based on Iron Mine ( we already have it ) + Trade.
_The utility of Trade is that a diplomatic economics interests appear and be usefull for R.P, and for a Castle/Town prosperity.
_Others things : We will see a new things, the goods robbery, Outlaws will not only robbs Chest (Lv.3 difficulty) or just robb peasants (Lv.1 Difficulty) but now will robb way, using ambush for robb Traders and enrich their crews (Lv.2 Difficulty).
_Traders will probably create caravans with others merchants and guards for improve their defense against Robbery.
_The Trade since the money exists was the things the more important in all societies (with public money), that is why our society is so much developped (too bad - that depends from some PointOfView, but that's not the way I want to talk about), a Persistent World with economy ( what we have ) is supposed to have merchants, or a "developped economy" cannot really exists.
_A real economy grows up.
_The Swamp Valley can be set up back (well done).
For exemple :

Exemple of Economy INTER-CASTLE v0.1 : too much tired for think more about some prosperity details, I am thinking to partage some more better solutions in future.
Actually, the INTER-CASTLE Economy is possible, but by using only : Bucket , Dagger , Iron Bar as goods, that's not a lot.
There is an other solution, but really hard to code, Trader has 35% reduction when they buy and they have 35% (from the Basic Price that normal people have) more into their sell price when they sell it, stockpiles has to be differents.. etc, I don't explain details, I think they are useless. Utility : Partage things for equality castle stocks.
I wanted to thanks you Vornne, for your Tolerance, you merite it ( from far ), for your help (toward me and for all the community too), for the work you did here, for your flexibility and managing alltime to listen suggestions, for your activity.
