Treasury size and loyalty

[Martok]

I can't recall if population or overcrowding is a factor in MTW (still haven't figured out how to get it working again) it is in RTW...

Fortunately, population/overcrowding isn't something you have to worry about in MTW.

So to think of it treasury size may very well affect loyalty but I think indirectly rather than directly,

seeing as how if you don't have the money you can't build and may your subjects happy..

I don't think the size of your treasury affects loyalty of your provinces, just with your armies. So long as you're not taxing them too much, I doubt the "people" care very much about how much money you have....the troops in your armies, however, care a great deal.
