What is Single-Player Game

This chapter explains the significance of informal and unwritten rules in order to show the connections among formal rules of play, formalized learning, informal and unwritten rules, and collateral learning. It argues that computer gaming’s rules of play include the formal rules by which games are played and the informal and unwritten rules within the magic circle of play where the games are played. Too often games are reduced to their formal rules of play and the collateral learning fostered by the realm of play is neglected. By examining unwritten rules, this chapter also connects to and informs other areas that rely primarily on formal rules, including educational gaming.
