Yeah, in fact, traditionally in China first cousins (on your mother's side) are seen as marriage partners of choice, partly due to the desire to increase the ties between the in-law families.

Like I said, I'd turn a blind eye to brother/sister relationships in the game, but if they'd implement an anti-parent/child-incest thing in the AI, it'd be sweet.

The other thing I wonder about is the promiscuity in the game. Not that I'm expecting VV to be a game about sexual morality, but I'm curious if anyone here had to explain the game to their kids (I don't have kids myself), when they see the villagers just having sex with everyone else in the village?
