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.
My paper Player Character Engagement in Computer Games was accepted to Games and Culture. Here is the abstract:
This article argues how players can control a player character influence interpretation and facilitate engagement within a game. Engagement with player characters can be goal-related or empathic, where goal-related engagement depends on affects elicited by goal-status evaluations whereas characters facilitate empathic engagement. The concepts of recognition, alignment, and allegiance are used to describe how engagement is structured in games. Recognition describes aspects of character interpretation. Alignment describes what kind of access players have to a character’s actions, knowledge, and affects. Allegiance describes how characters elicit sympathy or antipathy through positive or negative evaluation of the character.
