Treasury Compound Interest
This mod adds compound interest based on treasury, at rate of 1 percent per in-game year, enabling to gain huge amount of ducats over the centuries. For example, if you have 10k ducats you will receive 100 ducats for that year.
This is my first mod, so if you experience bugs or imbalances, please share your thoughts in the comments.
I am also planning to make a ET Submod version
