He legit said the game was polished, then says they're adding the family feature. Its not really super important for the immersion of the game. Looking at the live stream of Bannerlord, the game looks clean and ready for release. They're probably just being fussy now.
ALSO let game be released so the modders can run a train on it and allow them to add the ageing feature. All you guys have to do is update the game or provide links to it.
