Video game genres have always been a bit vague. Unlike film, where the genres have clearly defined frameworks, video games tend to base their genres on mechanics of design rather than plot elements. This isn't always the case — survival horror, for example, is a plot-based game genre — but a third-person action game can describe both Devil May Cry 5 and Uncharted 4: A Thief's End, despite the narrative content of each game being wildly different.
