This study focuses on examining the Online Game User Experience (UX) and the antecedents influencing it. We present a user-oriented research approach using the Repertory Grid Technique (RGT) to collect data across 15 semi-structured interviews, which were then analysed through content analysis, Interpretive Structural Modelling (ISM) and Cross Impact Matrix Multiplication Applied to Classification (MICMAC). The findings of the case study reveal 5 hedonic-oriented dimensions of Online Game UX and 6 interrelated antecedents. We propose a hierarchical framework to achieve a holistic understanding of the relationships between and amongst antecedents as well as dimensions of Online Game UX. The framework diagrammatically portrays the relationships of these context-specific variables by observing the direct and indirect chains of between the variables in the hierarchy. The study concludes by discussing the implications of these findings and presents two key theoretical contributions, one exemplary practical contribution, as well as directions for future research.
