Here's the mods I'd LOVE to see in Fallout 4: Sexout Breeder and/or Fertile Breeder! Think of it! With those mods, not only could you build your own settlements, but POPULATE them as well, without the need for attracting settlers (Note: I have no idea how people will move in to said settlements, or how said mechanics will work). I don't know if you can order villagers to do certain tasks (tend crops, build stuff, trade, etc) but, how badass would it be to build a settlement, populate it yourself, and order your 'children' to work (i.e. slave) away for you, their Mother Goddess?! Even more opportunities abound when you take into account breeding with the local wildlife: supermuntants and deathclaws for defense and attack (why guard when you can conquer) and as 'motivational speakers' (i.e. scare the shit out of the workers to make them more productive), brahmin for food and leather, the list just keeps going! Needless to say, I've been thinking about this since Fallout 4 was announced.
