This game inadvertedly "justifies" Caesar's philosophy and societal structure of Caesar's Legion.
What I mean is, the vault encourages you to have all female dwellers pregnant as often as possible. The vault is at it's most productive when this is the case. But when they're pregnant, they can't address or handle emergencies such as raiders or radroaches, nor can they explore. This means that all combat training is better done on male vault dwellers, and weaponry is better in the hands of a male, simply because a male vault dweller will never see a moment where they're incapable of using it.
Just found that funny, personally. Moment I realized that I thought "wow Caesar would be a really good vault overseer."
