The way the village is set up in VV can lead to really weird sexual relationships. Yes, I'm thinking of all the possible cases of incest.

Does it bother you? Or do you try to make sure that people don't mate within their immediate families?

Sometimes it's hard to control because the villagers do things behind your back. But I try as hard as possible not to have someone mate with their parent. It's harder to control between siblings and half-siblings, especially when you don't have a diverse gene pool to start off with.

Also, short of writing down names on a separate sheet of paper, you can't really encode all the lineage information in the name (unless you give them names like Lapita-Kokopu instead of a given name, since it's not all gonna fit on the line. And what would you call this person's child?). In some games I give them a Icelandic-style patronymic, like if the child of Okau is called Mali, I'd rename him to Mali Kokopuson/Kokopudottir (depends on the gender of the child).

That lets me know who are siblings and whose father is whom. But it doesn't help me prevent someone mating with his mother (the name "Mali Okauson" doesn't tell me who his mother is). And I can't fit the mother's name in the line (I tried using the mother's initial as a middle initial, but there are too many duplicate initials!).

So, in the next game, I decided to name the kids after the parent of the opposite sex. So, if Lapita and Kokopu had a son called Kayak and a daughter called Kissa, the son would be called Kayak Lapitason and the daughter Kissa Kokopudottir. This way I know that Kayak can't mate with Lapita and Kissa can't mate with Kokopu. I thought I was very clever.

Then I realised that I couldn't keep track of who are full siblings. >_>

Now I just pretend I don't see it when siblings mate. (I still try to break up people with the same hair colour, though, because that could be an indicator that they're closely related.)
