It's kinda difficult for me to writte 'cause I'm not from a english speaking country so have patience with me :P... Here are my opinions for VV3:

*The social structure of the villagers should be based on monogamy.
*The villagers should have some kind of familiy tree, that would be fun :P.
*A child villager should be like his parents.
*The villagers should be able to hunt and domesticate animals.
*The villagers should have pets.
*The villagers should be able to explore the entire island.
*The villagers should have some kind of nursery station.
*The villagers should be able to cook.
*The villagers should be able to have some kind of "memories" like the sims.
*There should be some kind of hidden technologies.

*THE VILLAGERS SHOULD SLEEP!!!

Well... that's all... I think...
Ah, I'm new here so, hello to everybody!!!
