My little Virtual Villagers people are determined to make my life more difficult. I realize it's not actually part of the game to keep track of lines of descent; nonetheless, I find it amusing. Except that they keep insisting on having sex and producing babies when there's not enough food to support them and when the labor of the women can't be spared for two years while they nurse, and, most importantly, timing their conceptions so that I can't bloody tell which kid was borne by which woman--until the child is two, it's just a swaddled bundle in the mother's arms, and you can't tell whose is whose until the child's put down. But because of the way time ticks work, I currently have three different women who are all going to put their children down at exactly the same moment. And all three women are different "clans" (I made that up too, and it's arbitrary), so the identity of the mother is actually important.
In the followup game, any child has its parents indicated on its "character sheet" page, which makes this sort of thing a non-issue. But for this instance, it's annoying me greatly.
