Manpower Effects
This mod adds a triggered modifier effect depending on your manpower. I really liked a similar mechanic in M&T, so I made my own version as a standalone mod.
At over 80% manpower, get 10% land morale (More people means more leeway to be selective in your army), 20% taxes*, (More people to tax), and -50% manpower recovery speed. (You’re reaching your upper limits.) At below 20%, gain 50% manpower recovery speed, (smaller base to work off of,) 10% less land morale, and 3 less unrest. (Less people to rebel)
*Trade goods might have made more sense as an economic modifier, but trade is already so good in this game, and taxes are relevant everywhere, even to countries in less trade – rich areas
This mod will make it less annoying late game when the ai take 10 loans to merc up at 0% manpower just to annoy you when they already lost, as their armies will now be a bit weaker. At the same time you might be able to manage the aftermath of a disastrous war that drained your manpower, with the unrest reduction and manpower recovery bonus. Intentionally draining your manpower is also now a valid tactic to prevent rebellion, as some did historically.
