NPCs vary greatly in importance, from the NPC innkeeper seen once by the player characters, to the NPC arch-nemesis who comes back time-after-time again for an entire campaign. While every inhabitant of the game's world except the PC's are NPC's, very few are given any detail by the gamemaster

 of his or her own can temporarily take control of an NPC. Reasons for this vary, but often arise from the player not maintaining a PC within the group and playing the NPC for a session or from the player's PC being unable to act for some time (for example, because they are injured or in another location). Although these characters are still designed and normally controlled by the gamemaster, when players are given the opportunity to temporarily control these non-player characters it gives them another perspective on the plot of the game.

Dependents

Many game systems have rules for characters sustaining positive allies in the form of NPC followers; hired hands, or other dependent stature to the PC. Characters may sometimes help in the design, recruitment, or development of NPCs.

 series, for example), a player that acts as the GM can "possess" both player and non-player characters, controlling their actions in order to further the storyline.

These "non-players" are often distinguished from player characters by avatar appearance or other visual designation, and often serve as in-game support for new players.

In early and less advanced RPGs, NPCs have only monologue. Code directs the appearance of a dialogue box, floating text, cutscene, or other means of displaying the NPCs' speech or reaction to the player. NPC speeches of this kind are often designed to give an instant impression of the character of the speaker, providing character vignettes, but they may also advance the story or illuminate the world around the PC. Similar to this is the most common form of storytelling, non-branching dialogue, in which the means of displaying NPC speech are the same as above, but the player character

; every one of their games is multiple-choice roleplaying. When talking to an NPC, the player is presented with a list of dialogue options, and may choose between them. Each choice may result in a different response from the NPC. These choices may affect the course of the game, as well as the conversation. At the least, they provide a reference point to the player of his or her relationship with the game world. True dialogues with NPCs are usually very complex, however after you talk with an NPC and turn right back around to talk with them again, no matter how many times you do this, usually they will give you the same exact conversation.
