Stories are a huge part of our lives. We narrate them, we consume them and subconsciously, we also learn from the stories we are told.
Although they are commonly used interchangeably, narrative differs from story, as the latter depicts a sequence in which events take place, whereas the former deals with the sequence in which these events are being told (may involve re-ordering). Although narrative is prevalent across all entertainment media, it is exceptionally powerful within video games, due to games' ability to forge non-linear / personalized narratives and their scope for a higher level of audience immersion.
This lens is industry standard.
