Was looking to make a game where I would remove characters that fell in combat.  Every one in the dungeon would be one race.  Breeding would be a large part of keeping the dungeon going.  It is hard playing not having masculine personalities.

I could have the women run the dungeon.  Any innocent male they get will be kept in jail.  All others will be gotten rid of.  If an invader reaches the jail cell, they will kill all the males in it.
