Hello all, I'm adding in a lot of new building for my upcomming verison of the submod, oen aspect is to make the economic buildings more diverse and interesting and part of that is adding in more buildings so that more of the resources in the game have interesting functions...
For example I now have salt trade buildings... which obviously requires salt resourcse to build... and in a similar ilk I have quarry and mason workshops... you can build them everywhere and they'll reduce the cost of future building projects a little... but if built at places with marbles they also give some trade bonus and a little more effect on the building cost down 
The point of this thread though, is to go through 3 aspects that i want to discuss... rivers.. silk trade and slave trade...
Rivers are a huge means of trade and A LOT of the pre-modern settlements were founded around rivers... 6.3 already have river hidden resource, but I plan on expanding it further, making it two level.. river and large_river, and expanding the river ports to 3 level.
So I would like to discuss the list of settlements where rivers or large rivers would be appropriate, some are fairly obvious (like Baghdad being large river) while others are not so obvious. at the moment my list is
(long list warning)
obviously this is probably incomplete... and some might be off.. would anyone with a better idea of the geography of those areas comment on what should and should not? basically any settlement that have some sort of navigtable river with some sort of history on river trade should qualify as having river... while obviously large river is more subjective...
In a similar sense. we have slave trade and silk road. both rather self explanitory. i have added in a hidden resource slave / silk_road to my edb , and i would wonder where they be appropriate...
right now my entry is...
Slaves (slave means the area is either a large exporting / trasporting hub or a huge market for them. small markets don't count)
while my silk road list (incomplete really, any major point of the silk road should count)
I really havn't had enough of a look at the appropriate turk / kwarezm provinces that should have them , would anyone help make some suggestion / comment on this ?
I could really use your help on these, all these buildings have been coded but I want a more thorough list of where i'm suppose to assign them to.
