the plot of the game. Some systems, such as Nobilis, encourage this in their rules. In less traditional RPGs, narrative control is less strictly separated between gamemaster and players. In this case, the line between PC and NPC can be vague. Dependants Many game systems have rules for characters sustaining positive allies in the form of NPC followers; hired hands, or other dependant stature to the PC. Characters may sometimes help in the design, recruitment, or development of NPCs. In the Champions game (and related games using the Hero System), a character may have a DNPC, or "dependant non-player character". This is a character controlled by the GM, but for which the player character is responsible in some way, and who may be put in harm's way by the PC's choices. Video games The term "non-player character" is also used in video games to describe entities not under the direct control of a player. The term carries a connotation that the character is not hostile towards players; hostile characters are referred to as enemies, mobs, or creeps. NPC behavior in computer games is usually scripted and automatic, triggered by certain actions or dialogue with the player characters. In certain multi-player games (Neverwinter Nights and Vampire: The Masquerade 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. More complex games, such as the aforementioned Neverwinter Nights, allow the player to customize the NPCs' behavior by modifying their default scripts or creating entirely new ones. In some online games, such as massively multiplayer online role-playing games, NPCs may be entirely unscripted, and are essentially regular character avatars controlled by employees of the game company. 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 other cases, these "live" NPCs are virtual actors, playing regular characters that drive a continuing storyline (as in Myst Online: Uru Live). In early and less advanced RPGs, NPCs only had 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
