Modeling Player-character Engagement in Single-player Character-driven Games

Abstract

This pilot study looks at how the formal features of character-driven games can be used to explain player-character engagement. Questionnaire data (N=206), formal game features (in 11 games), and ordinal regression were used in the analysis. The results show that interactive dialogue and cut-scenes showing the romances between the player-character and another character relates to higher character engagement scores, while romance modeling and friendship modeling relate to lower character engagement scores.

Keywords: ordinal regression, player-character, engagement, identification

ABSTRACT

What are the elements that aect story interestingness or consistency in single-player videogames? The question is approached by comparing player evaluations (N=206) of 11 videogames against a set of features derived by formal (qualitative) analysis. Ordinal regression was used to analyze the collected data. The study posits that dialogue system, romance, moral choice, appearance customization, and support for dierent play styles relate to story evaluation. Females tend to judge game stories more favorably and those with doctoral degree less favorably than players with other education.
