I had a small village to begin with - is hard to maintain of village or 10-15 villagers without fishing - but being small I was able to work with them all - made sure they all had at least Adept in everything but Breeding - this way I was able to change their preferences when I wanted to - when was waiting for crops - could change the pref of my 8 adults to research - when crops came up they would either start gathering on their own or I could change half of them back to farming. When came close to the "end" I change 2 to building and let them work on the temple and idol, then had them dig the treasure after that and water the field.
This took me weeks to do. I screwed up in the beginning and had too many villagers to support and they all died except 2 5 yr olds - one boy and one girl. So took me awhile to build them 2 them up. Can ask VI and IBTeri, I was nearly in tears trying to baby those 2 so I wouldnt have to start over again .
