The figures from the poster Modeling Player-character Engagement in Single-player Character-Driven Games in ACE Netherlands (2013):
Below is link to the data file and R code used to in the final models in “Models for Story Consistency and Interestingness in Single-Player RPGs” (in Mindtrek 2013) and “Modeling Player-character engagement in Single-player character-driven games” (in ACE 2013 Netherlands). The models q4 and q7 are used in the first paper and and the model q8 is used in the second paper.

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.
