Campus game specifically deals with how a social circle works within schools. Depending on the size of the school, social maps merge, and it is not always necessary to do a completely cold approach. Working the room, becoming a hub point for a resource within the school, and throwing cool parties at the right locations are all key to good campus game.
Campus game rocks!
