I agree the older people move annoyingly slow. I have had an older fellow breed with a much faster moving girl and she has already left the hut before he gets there. I think to make the game even more challenging there should have to be a wedding ceremony. The people marry for life that when their spouse dies they go through a grieving period. That would limit who breeds with who. It might be tougher to get your population up that way. There should be some information on the dtail screen to link the spouses. Along with that you could show offspring. Perhaps a way to prohibit family members from breeding, unless they are distantly related. What about electing a leader for the village, you know some type of government. Then again we would probably end up with unhappy people trying to overthrow the government.
