I posted an explanation of stats on Discord, I shall post them here too. Please take discussion to Discord if needed
An example of stats
Nation: Cheeseville - *player*
Government: Constitutional Monarchy
Army: 3/10
Navy: 8/10
Economy: 10/10
International Standing: 1/10
Administration: 7/10
Morale 9/10
An explanation for Stats, while most are self explanatory, there are four that need explaining.
Economy is the strength of your nations industry. It affects both your production of units and your morale. It also has some effects behind the scenes
International Standing is for NPC countries, the higher it is, the more likely they are to make deals with you. Note that this does not affect personal grudges or friendship
Administration is how good your empire can keep itself together. Low Administration leads to ineffective taxes and local militias taking charge. This in turn leads to rebellion and economic failure. The opposite is true for high administration.
Finally, Morale determines how close your country is to breaking. Whether this means a rebellion or a forced end to a war, it is a game changing stat.
