Great ideas you have there. Some of them have been mentioned.

As for married, lol I have this one breeder who only goes after one person, my master builder. Dont know what she will do when he dies. So I got all these male babies with painted faces and no hair!! I guess you would say they are "married".

In another game I made a male and female breeder, seemed to work out, as they only go for each other.

Elders do slow down. They walk slower, relaxed more then they did before they became elder, and dont work as much.(at least mine do).

Have kids help. Even young kids (age 8 and above) can pick crops or water crops. Have it so they dont pick as much as the adults. Or even clean beach.

I have an adult that goes to the school almost everytime I "play the drum" to praise the kids.

Cause of dead: Be nice if when one dies and you click on bones, it would say how they died.

I had went to one of my games (I have all players full) this morning and found 5 out of 6 kids dead. I had enuf food and 2 master healers sure would like to know how and why they died.
