Video game idea

Imagine the following team-based First Person Shooter: The map is a realistic model of a school, complete with blind spots and separated buildings. Random AI-controlled schoolchildren are everywhere, acting unpredictably as they panic and try to run to safety. Most of the players are randomly assigned to play one of the following (adult avatar) roles: Armed uniformed police officer. Armed teacher. Armed parent who happened to be visiting the school. Armed uniformed school guard.
