This thesis research explores the patterns of player-character relationships and player-character attachment in Animal Crossing: New Horizons (2020) and Genshin Impact (2020). The purpose of the paper is to fill in the existing gap in the literature concerning the psychological and social mechanisms of attachment that players form with non-customizable game characters. The research explores the nature of player-character attachment in its relation to game mechanics and broader social context, as well as its transformative potential.   The research relies on interdisciplinary mixed-methods methodology, drawing from the fields of psychology and anthropology. The first part of the research employs auto-ethnographic data on the authors' personal relationships with game characters. The second part involves a series of qualitative in-depth interviews with players of Animal Crossing and Genshin Impact. Thematic analysis with the elements of case-study methodology is applied to the interview data. The results of the interview analysis are compared between the two player groups, as well as to the findings of the auto-ethnographic inquiry. The main results of the comparative analysis suggest that players’ perceptions of characters in the studied games can be categorized as character-as-object and character-as-other. Further on, a distinction can be made between two types of attachment that players form with characters-as-others. The first one is player-for-character, focused primarily on a player’s relatedness and empathy towards a character. The second one is character-for-player, where a game character is perceived as a supporting and caring figure that transcends the boundaries of the game. The relationship types are not mutually exclusive, and both of them have been found to have transformative potential.
