That's a good idea. I also like karema's a lot, too. ^_^ I have some more ideas:

- If there were domesticated animals in the game (like what karema said) maybe there could be an animal training puzzle, or an animal training technology.

- If they still have a Spirituality technology in VV3, then maybe if they have a high enough Spirituality level, they could try to see spirits of the dead, or maybe if you honor the dead a lot, your villagers could see a ghostie or two. (Stupid idea, I know, but it would be cool...) It could be a puzzle, too, I guess.

- Maybe there could be higher populations.

- Maybe we could customize our villagers (for example, we could choose their face, hair, their clothes, etc.)

That's all I have for now...
