what a great game!! keep up the great work!! (patiently awaiting the PC version of Plant Tycoon)

i love all the suggestions posted already!!

i'd like to suggest:

Make females too old to breed just as villagers are too young...its sad that the baby dies with the mom. 75 year old women shouldnt be able to get pregnant, its just crazy!!

love the family tree idea (like in fish tycoon)
