More interaction between villages. Make it so they won't have babies if parenting isn't clicked. I hate it when I do that by mistake.

Make it so that if parenting isn't clicked, they villagers will bond. Maybe chat, joke, play a game, have a race, join FC....lol

This goes double for kids. Never understood why you couldn't get them to play games together.
