NPC Children would be so fun since nobody wants to roleplay anymore. It was be entertaining to watch them grow up and live in the house we have. We can customize their personality traits to what we would like or on what much money our house is worth. For example if our house is worth a lot they would be more expensive and spoiled with a ruder personality. If it was less expensive they would be more humble and understanding. Therefore having this as a feature would be great for players all around.
