This study aims to construct a systematical approach to classification of narrative usage in video games. The most recent dominant approaches of reading a video game text – narratology and ludology - are discussed. By inquiring the place of interactivity and autonomy inside the discourse of video game narrative, a classification is proposed. Consequently six groups of video games are determined, depending on the levels of combination of narration and ludic context. These Six Degrees are defined in detail and example video games are analysized for each. The conclusion composes a six degrees reference system that could be utilized in various fields such as video game design or video game studies.
