Games provide a variety of experiences for players. Currently, research focuses either on games as undifferentiated wholes, or on a feature-level basis where findings are difficult to generalise. However, specific gaming experiences cannot be explained from these approaches. Open world games in particular are a popular game type known for giving players high levels of choice over what they do, thus enabling uniquely different experiences. Current approaches cannot capture what about this gaming experience players enjoy or why. To do so requires a ‘contextually-specific’ approach, demonstrated in this paper.
