when players will randomoly spawn as women, male and female players should be able to craft one or more children.
the children have in AI based on their age (24h = one or two years, and yes, also players should grow old)
after a certain age, you can decide if you want to play with your regular avatar, or with the new childish avatar in common with your friend.
the new born can’t respawn after death.
How about growing armies of children well fed to defend your home while off-line, and to help raid your enemies?
an AI scripting UI could be implemented to program your army of child-bots, omfg it would be amazing.
