Sorry if this has already been brought up, but I couldn't find it.
In CK1 one usually ended up having a very large amount of children, who all grew up, and required titles and so on. Rarely did I have problems finding an heir amongst my kings children. However, that was really very unhistorical and unrealistic. Child mortality was massive in the middle ages, and caused a lot of concern about the inheritance of the throne. As an example, the Danish king Erik Medved (1274-1319) had 14 children, and none of them lived past the age of 1. The wife of Valdemar Atterdag (1320-1375) had one child every year, for 12 years, and only 3 of them survived the first year, and only one, the later Queen Margrethe (later Queen of the Kalmar Union), survived her parents.
So...I'm sorry to say it, bit I think that we should have many more dead children in CK2, compared to CK1. Let legitimate heirs be a real(istic) problem.
