There are only a few tasks for the villagers once the game is at it's max - harvesting, fishing, fixing huts, laundry, burying the dead, breeding, healing, etc. All the scientists fill in wherever. Therefore, the villagers really don't need me anymore...there is nothing more to accomplish...thus waiting for VV2 - but the Thanksgiving mod is fun!
Right now, I have a game that has been going for a couple weeks and about 50% are "elderly" and when breeding, the baby is born BEFORE they get into the teepee...too funny!
