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.



This is an old paper published in 2003 containing an early version of character recognition framework developed further for my thesis. This version contains some edits compared to version available in Digra Digital Library due to quick html conversion (no foot notes, tables are lists, etc.).

ABSTRACT
Interpretation of characters is a fundamental feature of human behavior. Even with
limited information available, people will assign personality – even to inanimate objects.
Characters in computer games will be attributed personality based on their appearance
and behavior. The interpretation of these characters affects the whole game experience.
Designing the protagonist character in computer games is different from the design of
static characters (e.g. film or literature), because the player’s actions will affect the
nature of the character. There are, however, many ways to control and guide the actions
of the protagonist and thus the character’s nature. By setting goals, scripting pre-
defined actions and choosing what kind of actions to implement, the game designer can
restrict the player’s freedom. This, together with the characterization of the character,
will affect the interpretation of the character.

Abstract. Lies and Seductions is a computer game in which a player controls
Abby, a character on a wager to seduce a rock star who has promised to stay a
virgin until marriage. The game is loosely based on the story of Les Liaisons
dangereuses (Dangerous Liaisons). The game is a design experiment exploring
how to use social relations, seduction, and tragedy as meaningful gameplay
content.
Keywords: Computer game, social interaction, seduction.

ABSTRACT

Contemporary computer and video games utilize characters in large extent. However, game research literature says only little about how to design gameplay so that it reflects characters’ personality; mainly focusing on the narration and graphical presentation of the characters.  This paper presents a character-driven game design method, which uses ideas from dramatic character design to include gameplay into the design process. Based upon previous work on NPC design and a new analysis, several design choices regarding gameplay are identified. These choices are described as gameplay design patterns and related to how specific features in a character design can support gameplay. In conjunction with the patterns, the concepts of recognition, alliance, and alignment are used to introduce the method and provide examples. The paper concludes with a discussion on how the method can affect the overall gameplay in games.

ABSTRACT
This paper explores how games can be designed to make the social networks of characters as part of the gameplay. We start with a premise that game characters and social relations between them are import in games. We examine several games and derive gameplay design patterns from those games. Models from social network analysis, actor-network theory and Egri’s model for dramatic conflict is used to focus the analysis. In addition to isolating design patterns from existing features of the games, we look situations where game structures do not support social networks or conflicts as proposed in above-mentioned theories. Patterns identified include Competing for Attention, Gain Allies, Social Dilemma, Internal Conflict, and Social Maintenance.

1. INTRODUCTION
As social creatures, humans easier to engage in a game and narration when characters portrayed in these have social relations to each other, or in other words that the relations between characters form a social network. This is common knowledge within scriptwriting theories for theatre and film (see, e.g., [6, 7, 17, 19]), and these theories are also applied to creating games. However, social relations in games are typically part of the storyline (see, e.g., Thief II: The Metal Age [34], Dead or Alive 3 [44], Silent Hill 3 [45], and Half-Life [48]) and games typically do not let players directly act to influences those relations, instead letting them be consequences of other (most commonly physical) actions that are shown through cut-scenes. One example of this can be found in Quake 4 [22] where the relation between the player character, Matthew Kane, and the other characters in the Rhino squad are only changed in the cut scenes. No possibilities to do so are available during gameplay, including making it impossible for the player to terminating the relationship by killing the other team members. When players are given direct choices to influence the relationship this is typically done as explicit choices between a limited set of alternatives, and the effects of these are localized and seldom have the complexity of nuances of real social relationships, including how one change in a relationship can propagate through a whole network. Although these limitations typically make sense from gameplay or storytelling point of views, we think that the above-mentioned ways limits the design space of games, and having further alternatives would expand the expressive design space of games.

ABSTRACT
Descriptions of humans require several qualities for people to experience them as believable: human body; self-awareness, intentional states, and self impelled actions; expression of emotions; ability to use natural language; and persistent traits. Based on these we analyze non-player character Claudette Perrick in The Elders Scroll IV: Oblivion to detect how these qualities can be created in the interactive environment of a game. We derive the gameplay design patterns Awareness of Surrounding, Visual Body Damage, Dissectible Bodies, Initiative, Own Agenda, Sense of Self, Emotional Attachment, Contextual Conversational Responses, and Goal-Driven Personal Development, which point to design choices that can be made when designing believable non-player characters in games.
