It would be great if pawns can find new passion as they live on. This should at least be true for younger pawns like teens and young adults. Maybe have the passions cap throughout life, like a pawn could have say 5 maximum passions (or 7 or all of them, but this only through perks - Polymath hint hint), and based on how old they are they should be eligible for developing passions. Maybe they could also lose cerain passions as time goes by. I'm just jotting this down fast because it seems a great idea, it could enhance the stories so much. Other people are welcome to chime in. It also seems like it could be implemented without beaking the game making you overpowered. Maybe pawns could develop passions based on events. Like if someone kills a relative of theirs i see an opportunity for a passion in combat to develop. Maybe creating a masterwork item. Do chime in!
