Max Province

Overview
Max Province is a mechanic that keeps a country in its supposed size. Every country has their own limit of max provinces. If you own more provinces than your country's max province limit, you will gain yearly revolt risk and Overextension. The amount of yearly revolt risk you get for overextension per province is variant between countries and eras, mainly because of technological differences.

Trivia

 * Overextension was only 0.3% per province when War Universalis 2.
 * Ever since the overextension percentage buff, it's unbearable.
