And speaking of children's games, I suggest that you obtain a copy of The Children's Story by James Clavell. This little parable was written in 1963 and takes place after a coup d'etat. The setting is a classroom where Clavell shows how easy it would be to convert the hearts and minds of children from one form of government to another. You'll be shocked to see how long it takes.
