Substantial Towns and Cities - BT

This mod allows nations to change their trade goods when their provinces reach 40 development, this will temporarily reduce the goods produced. The list and their requirements at the moment are as follows:

• Silk - Allowed if nation is 800 development, global trade is embraced or the province is in places where it was historically
• Glass - Allowed if nation is 200 development and renaissance is embraced
• Cloth - Allowed if nation is 100 development
• Paper - Allowed if nation is 200 development and renaissance is embraced
• Dyes - Allowed if nation is 400 development
• Incense - Allowed if nation is 300 development and feudalism is embraced
• Salt - Allowed in any coastal province if total development is 200 and renaissance is embraced
• Books - Allowed if nation is 200 development and renaissance is embraced
• Option to not change trade good and gain a temporary goods produced bonus
• There is an option to wait for another trade good to become available


It has a city system which gives the province a modifier when it reaches 40 development. The modifier makes all provinces closer to grasslands reducing development cost in most terrain types, gives them +2 local unrest and +5 local trade power. In the future this will allow the cities to have special events happen to them.


It also adds new buildings unique to capitals in the form of modifiers. 3 different types are able to be build at game start with a max of 5 after 2 events. Here is a list of buildings available:

• Military -1% army decay yearly. Requires 50 development and 300 total development (200 ducats and 100 mil)

Gold cannot be changed
Event for generating a level 2 CoT in the capital if one isn't already there, this is only possible once per game and requires 600 total development and 50 development in the capital. This costs 100 admin and 300 ducats.


Future Plans:
More unique city events such as fires, development migration to the city and temporary goods produced fluctuations
Changes to the current "sack of ****" event so it can only happen in cities hopefully providing a incentive to put forts on the cities to protect them
More types of trade good available to the cities (not new non-vanilla goods)
Better requirements for trade goods and capital buildings (ideas groups)
More capital building types like having to choose between -5 tech cost/ -5 idea cost for the university
Different levels of capital buildings (start with -2.5 tech cost and then upgrade to -5 tech cost)
