A role-playing game is a game in which the participants assume the roles of fictional characters and collaboratively create or follow stories. Participants determine the actions of their characters based on their characterization, and the actions succeed or fail according to a formal system of rules and guidelines. Within the rules, players can improvise freely; their choices shape the direction and outcome of the games.

Shooter games are a subgenre of action game. Because "shooters make up the majority of action games", it is a fairly wide subgenre. It includes many subgenres that have the commonality of focusing "on the actions of the avatar using some sort of weapon. Usually this weapon is a gun, or some other long-range weapon".

A sports game is a computer or video game that simulates the playing of traditional sports. They are extremely popular, the genre including some of the best-selling games.

A strategy game is a game in which the players' decision-making skills have a high significance in determining the outcome. Many games include this element to a greater or lesser degree, making demarcation difficult. It is therefore more accurate to describe a particular game as having a certain degree of strategic elements, as in being mainly based around strategic principles.
