Not sure if this was suggested or not - I don't remember reading it.

Chickens. I would love to see some chickens. Have the children find the eggs (like the mushrooms) and let the chickens breed if they are not eaten. It would be a challange at the start of the game to NOT eat them as food has not been developed yet and there are only berries.

I would also like to see a 4X speed setting. There are times when I feel I NEED to speed things up = just before I go to bed and need enough tech points to help them survive etc.
