Hello all, it’s time for another DD! Today I’m going to tell you about the Prosperity system, which is a <secret DLC> feature. Prosperity is rather like the opposite of Depopulation, which I have mentioned in previous DDs. In essence, provinces which have not been sieged, raided, or ravaged by disease for a long time will begin to Prosper, and gain certain bonuses- such as extra tax income and faster replenishment of levies.
To go into a bit more detail, provinces will have a hidden value which increases every year based on things like random chance, the terrain of the province, the ruler’s stewardship, if the realm is at war, and if the province is the ruler’s Crown Focus. “Crown Focus? What’s that?” you ask? Well hold on, I’ll get to that soon. When this value hits certain thresholds the province receives a modifier and the owner is informed that the province is Prospering. If things continue to go well, there are up to 3 levels of Prosperity to be gained. On the other hand, if the province is sieged, sacked by raiders, or infected by an epidemic, the Prosperity level will be reduced. If a province is Depopulated, all Prosperity is wiped out.
Various other factors can also affect the Prosperity value of a province, many decisions and events which involve building things, deals with merchants, holding feasts and tournaments, and that kind of thing now also have a Prosperity increasing effect, typically in your capital if another province isn’t involved. For the Norse, there’s also an event which can trigger when a fleet returns with loot which gives the capital a small bonus.
And finally, there’s your Crown Focus. Independent rulers who are Dukes or higher, and of sufficient size can set one of their Demesne provinces to be their Crown Focus - somewhere the ruler is devoting more of their attention to, which causes an additional yearly increase in Prosperity. Further, if your Crown Focus province has achieved the maximum level of Prosperity there are some new beneficial events which can fire there. The Crown Focus is also the cause of the crowns seen on the map in some earlier screenshots, although we’re thinking of showing only your own Crown Focus icon to avoid map clutter.
That's all for now, but next week I'll mention the new Narrative events <secret DLC> will add.
