The Idea behind Regional Goods was to get Trade.
But Demand and Supply is just too unreliable for any Big Trade to happen with this.
So how about this.
Every Region should get 2 or 3 Trade Goods that can ONLY be Produced there.
These are not Required for Building and Serve no Purpose for Playees. But instead would be Luxury Items Sold to the Crown in the Capital.
However. They can ONLY be Sold in the Trading Posts in the Capital.
The Desert Region South can Produce Regional Glass Wares.
These can only be Produced there.
They require Material Preparation 90
And there is 3 Stages.
Crate of Glass.
Weight 100 Stones and worth 20 Silver Coins.
Requires only Some Boards for the Crate and some Produced Glassware that can only be Produced there.
Crate of Professional Glassware
Weight 200 Stones and worth 50 Silver
Requires the new Regional Glassware and some Metal Parts (Metal parts are just basic Metal Band etc) as well as Boards for the Crate.
Trunk of Luxurious Glassware.
Weight 500 Stones and Worth 2 Gold Coins.
Requires Regional Glassware as well as Steel Materials and some Gold/Silver.
In the Mountains in the North you cant Produce this Glass stuff.
You get a different Good.
For example Mountain Herbs.
These Snow Herbs can only be found there.
Again 3 Stages.
Being just a Crate of these Herbs.
Being Crate of some advanced Herb Preparations from Medicine Skill.
Being a Trunk of Pristine Potions of Longelivety.
Each Region gets its own Good which can ve Produced ONLY in that Region.
And which can be Sold ONLY in the Capital.
Oh and the Capital Region Good will be Wheat and Flachs. Which will be way Cheaper than the Goods from other Regions. As they can be produced closeby.
Of course the small far off regions would get the most profitable Goods
This would cause 3 Major things.
Guilds of each Area would Priduce their own Good and then Transport it to the Capital.
Creating Chances for PvP and Banditry
Guilds would have a way to gain Larger Sums of Money in exchange for a Risk.
Land itself would become valuable and give Guilds a Reason to Fight Wars over it.
Because that small Patch of Land in the far away Region gains super high profits.
And that place directky beside the Border counts for the border and has such a nice and short way to the Capital
As an side effect.
Trade would also be buffed.
Cause these Guilds need some additional goods for the most profitable trade.
And for them these Goods get a value that they dont have for the others.
Thus giving others a reason to sell and them a reason to buy.
The Desert Guys for example will likely be buying Gold and Silver or even Wood as its hard to get in the desert and they themselves can make way more money out of it if they dont need to farm it themselves
