I like many of the ideas that have been posted and am just re irritating but i think weather, times of day and night, sick villagers go to the hospital on their own, children learn to pick up valuable items on their own, the adventure idea is pretty cool to, and here's one from me villages can interact with eachother.example you have a friend who has a lot of food and you don't, send them a villager with a note saying" we need food" the villager will have what ever data with him so that your friend can send you what ever you asked for or can deny you the whatever and just go on living with his/her village.
