The first dev diary, while old, said the portraits would age.
The characters have three portraits: child, young, and old. Which means that on your birthday you go from looking like you did when you were 20 to looking like you will when you're 80. It's better then CK1, but actual aging so a 35-year-old looks different then an 18-year-old would be even nicer.
This is very nice. But I confess to one worry. Suppose I am playing a larger realm, perhaps even a kingdom. If I have to manage this level of intrigue and character planning for my entire court, wouldn't it get to be overwhelming after a while?
The AAR is short, but since Orabilia was born in 1080, and the AAR ends in at least 1111 (two years of war after her claims were forged in 1109), there're 30 years of gameplay here.
As a Count-level character you probably won't have enough intrigue to deal with, unless (unlike our heroine) you have multiple Baron-vassals. That is, after all, why Baron-level characters were added, but made unplayable. If you try to blob as Emperor of all Europe you'll probably be overwhelmed, but that's WAD.
But if you're just playing France you'll be fine.
