House/Dynasty Age should be connected to the age of the custom character.
Whenever you make a custom character in CK3 their house is always the same ages either 867, 1066 and 1178. To me it makes my character feel fake, which he of course is, but if we’re going to make this game the immersive and character driven game that paradox wants it to be I think that this is the direction that’s needed. For example, let’s say that I want to play as a Old Frankish house in 867, I simply cannot as my house will always be from the late Carolingian Period rather than earlier, to me the issue seems to be that the house age is always the year the game starts rather than when the character was born. Let’s say I start as a 120 year old character in 867 the house would then be founded in 747. This change is fairly simple and would greatly improve my immersion in CK3. Thank you all for listening to my ramblings about something that I’m sure most of you don’t really notice or care about. God bless.
