My high school world history teacher ran a game like this for the class. He booked a whole week for it. After two days we had destroyed the world in a nuclear war. He made us sit quietly in class for the rest of the week as punishment! What a great lesson though in how terrible people can be.

I upvoted you, but really it's meant for your teacher. It takes guts to follow through on stuff like that.
