First-person (video games)
In video games, first-person is any graphical perspective rendered from the viewpoint of the player character, or from the inside of a device or vehicle controlled by the player character. It is one of two perspectives used in the vast majority of video games, with the other being third-person, the graphical perspective from outside of any character ; some games such as interactive fiction do not belong to either format.

First-person can be used for virtually any genre; Zeno Clash (screenshot above) is a beat 'em up in first person, an unusual choice for the genre.
In 3D video games, a virtual camera system aims at controlling a camera or a set of cameras to display a view of a 3D virtual world. Camera systems are used in video games where their purpose is to show the action at the best possible angle; more generally, they are used in 3D virtual worlds when a third-person view is required.
