The main focus of game developers has for a long time been the audiovisual fidelity of the games, but some researchers claim that artificial intelligence (AI) will be the next step in improving the player experience in games. However, there is as of yet a lack of ways of measuring comparing the believability of non-player character (NPC) behavior in games. In order to rectify this we present a method which can be used to create a typology of NPC behavior believability. Our method uses the Carley & Newell fractionation matrix to describe how advanced the behavior of a game’s NPCs is. This is then recorded in a format that can be compared by simple logic operations.
