Yes, I like that idea. Maybe you could be able to construct a Pen, to hold animals that you can breed, and gather things from (if there were sheep, you should be able to gather the wool and use it for fabrics) and such. I personally adore animals, and it would be very cool if we had animals. Also, I don't know about you, but I can get pretty bored when I'm waiting for certian things to happen. Animals would need to be taken care of by a Herder, or a Shepard, or someone. That could be another Skill.

Maybe there could be an actual school, where children from six to fourteen could actually learn some of the skills that the parents were best at. That would keep them away from the adults, and keep them contained.

Another one I thought of is that there could be a Nursery, where once the mothers give birth, they can drop their newborn child off and go and do their jobs for short periods of time. I think that it is somewhat silly to hve mothers have to spend two whole years carrying around a baby, and not do their job. The Nursery could have up to five workers, depending on how many babies there are (each one could handle around eight babies or so at a time). This could be another Skill.

Ya, I know I have alot to say, but I might as well do since I am here. This is the last one.....
.....Seasons.
Certain crops should only be planted in certain times of the year, and animals (assuming that we will have them) should give birth in spring. Also the villagers behavior could go with the seasons, such as in the summer, villigers will tend to hang around in the shade, and in the winter, they will sometimes retreat into buildings for warmth.
