Hello and welcome to another Developer Diary about getting sick and dying! Previously I talked about this in the personal sense, but today I will tell you what we have done to Epidemics.
In our upcoming but still unannounced DLC, we have added many more scriptable values to Epidemic diseases which allows us to do many more interesting things with them. I’ll skip the technical details here, but Epidemics can now spread along the Silk road when present, and are more likely to spread to rich and coastal provinces while being less likely to spread to poorer inland areas. Different Epidemics can have different speeds and likelihoods of spreading, as well as different maximum provinces they can spread to and durations to last for.
Epidemics also have another effect now, they can cause Depopulation in a province. Depopulation is a modifier on the province which reduces tax incomes, levy/garrison sizes, and supply limits. Different diseases have different chances of causing Depopulation, and the effects can remain long after the diseases have died out.
Of course, I can’t talk about Epidemics without mentioning The Black Death, since it was a somewhat notable event in the CK2 period. In the past, the Plague hasn’t been too impressive, but now… well now we have made some changes:
while it's possible for the Plague to come from central asia and bypass India, in this instance it arrived in the North-east of the subcontinent and spread throughout it and outwards. Meanwhile, England has Smallpox.
As well as making The Black Death larger and more deadly, we felt it was a shame you’d have to play until 1300 to experience it. So, in our generosity we made The Black Death more dynamic and there is now a chance for a major outbreak to occur 200 years into any game, regardless of startpoint (and the 1300 outbreak of course remains possible too). After a major outbreak has happened the disease becomes endemic and may break out again, but likely on a smaller scale. I should note that the dynamic Plague is a Game Rule, so if you want to restrict the first outbreak to 1300+ it’s still possible.
Is it all doom and gloom in this DLC? Well no, not entirely. As I mentioned previously, Court Physicians will try to treat your illnesses, and you will also be able to build Hospitals, and/or go into Seclusion to attempt to avoid infection - but those are topics for a future DD. Until then, contemplate your mortality.
