Previously a small, well-managed family was a key to victory.
What? Since when? I've always gotten through fairly well with families that put rabbits to shame.
Because paying hundreds, sometimes upwards of a thousand gold for a hospital upgrade (And thus basically neglecting the entire rest of my realm unless I'm raking in a hundred gold a month) just so my fifth consecutive ruler won't die at twenty is so fun. Contrary to popular belief, people actually lived for a decently long time if they survived infancy. I'm fine with diseases and whatnot, I just think the random event diseases should be toned down a lot.
Hospitals aren't going to help much without a good physician. If they're not like 17+ learning (Renowned Physician optional since they can get that), then wait for the next one. Other then that, close your gates when an epidemic comes near.
Seriously, with a good physician, some pets (hunting in focus is OP with the added health events and dog), and closing the gate you don't really need hospitals until the Black Death brings it's nasty self around. I've yet to have a character in my current game ( Count Robert Capet of Bourbon in the Charlemagne start) I've yet to have a ruler not last to their sixties and courtiers not stick around for a while. However, it does seem like unlanded and baron level unmarried characters are set to die quicker... Probably part of the reason the game runs better.
Cancer has always been relatively rare, mostly affecting older people. It's not to say it didn't exist - but they have done studies of old bones and found relatively few examples of cancer in Middle Ages remains. Of course, there's evidence of Cancer going back to neolithic times, but the chance of someone dying by this was extremely low given all the other ways to die, and given the age range it usually afflicts.
Wait, cancer isn't weighted to effect the youth less often? Even by a small amount?
Anyways, I still find the loss of my first daughter/child and her mother to cancer as the most tragic thing I've experienced in CK2. The little one came down with it at the ripe old age of 4, fought to adulthood, got married, and died shortly afterward. The increased death rate from diseases and epidemics has made me finally value life in this game. I'd call that "Mission Accomplished."
*But I too think there needs to be some adjustments needed. AI needs to focus building few hospitals! It should at least make It level1 with 1 or 2 upgrades. I really feel like cheating when AI doesn't do hospitals. Please tweak that AI.
Besides this, it would be nice if we could order the physicians to continue treatment of relatives and councillors. I'm keeping them around so they might as well be useful when I'm not sick.
