As far as clubs, one thing I will do with them is to use the club system to bring my sim's extended family home to visit. So when the kids grow up, move out, and are living on their own, I can easily bring everyone back to visit and keep in contact with each other. I have even used the club system to get the children to do their homework, do chores, and easily get my larger families to do things together with each other.
Used the club system so that the children/teens in the family can easily invite their friends over and have a slumber party.
If I have a single parent who is raising their child alone, and the other parent is in the game. I will use the club system to bring the one not living in the household over so they can visit and interact with their child.
