I'd like some kind of family tree (besides a 'child of' thing that vanishes when the kid's 18). Granted that in VV it's more likely to end up as a family bush, but still...if you could pick one villager and trace their roots right back, that would be good.

On the marriage thing, it would be good if you could also grow your tribe a little by having other members show up (Something along the lines of 'Tapu has heard of Aponi's great beauty and has travelled from his village to wed her. Does Aponi accept?' (Just thinking of ways to avoid a little too much inbreeding ;))
