Play-Persona: Modeling Player Behaviour in Computer Games

game variables should be monitored in order to gather usable game metrics data for profiling
players’ behaviour.
Fig.2 4th dimensional possibility field
Let’s postulate that players can be scored in each dimension only in two ways: positive and
negative. Exploding the possibility field is a matter of elevating 2 (the possible values) at the power
of 4 (the dimensions) obtaining a total of 16 possible profiles (fig. 3). Amongst those profiles there
are only few that become interesting because they are so extreme that delimit the possibility field
of player behaviour.

helping or healing team mates will be classified as a “Grunt”.
