Genres in video games are generally defined by either the predominant action that the game is built around or on some other factor that defines the experience of play. Take shooters as an example. We call them that because the player spends most of their time shooting things. Originally these games all looked similar, usually top down or side views of a gunship or other shooting platform moving on a 2D plane, but as technology improved and allowed for more options, so did the specificity of the nomenclature surrounding the genre. Shooters can now be subdivided into first person, third person, side-scrolling, light gun, twin stick, and so forth. Now why in the first two do we specify perspective over some other aspect? Side scrolling is related to level design and the term “twin stick shooter” refers to a control variation.
