GAME VERSION 1.1.3 BETA

If you think this is too much for your PC or conflicts with other mod you play check lightweight version of this mod:
https://steamcommunity.com/sharedfiles/filedetails/?id=3629755859

USE THIS VERSION OR LIGHTWEIGHT BUT NOT BOTH !

If you get crash on startup for continued game, check for updates of River trade locations mod – it can crash game, but there is backup.

This mod makes radical changes to mechanics of the trade, changing the system entirely.
What this mod do:
Revision of trade cost: distance cost 2.5x higher while river and sea trade now offers more significant distance reductions.
Same applies to market access with additional change of river flow bonus(it now travels better upstream than downstream)

Change to distance multiplier for trade capacity : In vanilla it was 1+small multiplier (usually in range of 1-2) which favored long range trades over neighboring market center.
Since this 1+formula was hard-coded I divided transport cost of every good by 10 and increased trade cost multiplier by a lot, which now scales from x1-x30 , where x10 is similar to vanilla experience. Trading between close trade centers is cheap and you can push big volume of material over the sea or downstream a river (trades like London-Brugge are super cheap now) while long overland trades can handle only high value goods with big comparative price differences(going Krakow -> Kiev 10x harder than Krakow->Gdansk along Vistula river)

Steep increase in trade difficulties makes makes market access a lot limiting factor.
To counter this I’ve added a lot of missing trade centers (almost 200) in various places – to offset this (and save some PC performance) I decreased trade range, as there is no point in long rang overland trade, and sea trade is much cheaper. Bigger countries now starts with more than one trade centers. Trade centre gives only +1 trade capacity (from +2 in vanilla)
All markets are now positioned in important trade routes. I’ve placed them in locations which
– are at least town(if possible)
– tend to be at crossroads of trade routes or along major rivers
-were historically important trade cities(even if not at game start)
It turned out to be quite easy, as most city i wanted to add were already in place, just waited to be added as market center- I didn’t (almost) add a single city or town to map
If you don’t like my choice you can easily chose different cities or just remove some of them. (just edit main_menusetupstart3_market.txt file in mod folder)
But usually they have in game purpose.

Another new mechanic – vassals now scale their trade protection by inverse of loyalty.
In vanilla each vassals have 0 market protection to liege and full 50 market protection(scaled by control) to other countries.
What market protection does is makes province choose different market center (with lower market access) just to be loyal to your country.
Why would disloyal vassal do that ?
Now they scale this behavior by loyalty – if they are 100 loyal, they act as in vanilla. If they are at 50 loyalty – they only gives half the market protection.

Changed natural harbour suitability – it gives only minimum harbour capacity, but allows for building multiple levels of wharf (was 1 lvl only building). Cost of embarkment incresed. Together it will be much more difficult to conduct sea trade if no port buildings are in your market center to further discriminate between land/sea trade centers

WHAT WILL MOD DO.: Trade system should run itself, trading sensible goods along historical routes. Overproduced goods will diminish in price, while absent goods will be high in demand. There will be plenty trade centers so every part of the Old World seems interesting to play. Market Stockpile will break UI as for now, but it makes trade realistic. (maybe iI will fix the UI someday, help will beappriciated)

What this mod WON’T do: Many trade centers and higher instability of prices will drive you mad if you want to do trades manually. LEAVE IT TO AI. This mod don’t affect economy so if map is not balanced with goods (and Vanilla map isn’t by a lot) you will end up with a lot of goods dirt cheap. This isn’t a mod to fix them all. Economy will need another mod. I have some distance plans for another mod to tackle with economy.

WARNING:
Adding new modifiers and 200 new trade centers takes a toll on game performance.
Ain’t gonna lie, it’s not for 10 years old laptops. I play on fairly recent gaming rig (i7-12700k with 32gb RAM) and it crunches for like 2 seconds every month but i find this trade system so much more enjoyable that i find it worth it.

Mod is still under heavy development – a lot of balance, and optimization is still needed but i need more people playing and giving feedback so please do not hesitate and comment.

Required and recommended mod:
European Rivers Expanded (highly recommended/required)- for better rivers
River trade – locations fixes (highly recommended/required) – my minor mod supplementing ERE, but for location shape, to better follow rivers
Market Stockpiles(highly recommended for powerful PCs) – my other mod, with additional mechanics for market stockpiles. it adds another layer of calculations. I personally play with this mod.

Historic RGO – Global https://steamcommunity.com/sharedfiles/filedetails/?id=3602513956
or some other RGO balancing mod is highly recommended as Vanilla setup is unbalanced.
This mod don’t change location_templates file so it’s fully compatible with those kind of mods

Feel free to comment,give suggestions, ask for changes.
Change mod locally, and post your findings – I’m open for balance changes.
I’ll later try to post lighweight version, with more vanilla like market access and without additional market centers – just mechanics – for mod compatibility and performance
