The document describes a study that used the Personal Construct Theory (PCT) to develop a methodology for evaluating player experience in video games. Researchers conducted interviews with 64 students to elicit constructs for describing video games without imposing predetermined categories. This resulted in 570 constructs which were grouped into 23 dimensions that capture how players perceive and evaluate games, such as in terms of ability, dynamism, engagement, and emotion. The dimensions included criteria from professional reviews and academic theories. Players were then asked to rate games based on the dimensions to analyze similarities between genres.
