Game Moderator

A gamemaster (GM; also known as game master, game manager, game moderator, referee, or storyteller) is a person who acts as an organizer, officiant for regarding rules, arbitrator, and moderator for a multiplayer role-playing game. They are more common in co-operative games in which players work together than in competitive games in which players oppose each other. The act performed by a gamemaster is sometimes referred to as "Gamemastering" or simply "GM-ing".

The role of a gamemaster in a traditional table-top role-playing game (pencil-and-paper role-playing game) is to weave the other participants' player-character stories together, control the non-player aspects of the game, create environments in which the players can interact, and solve any player disputes. The basic role of the gamemaster is the same in almost all traditional role-playing games, although differing rule sets make the specific duties of the gamemaster unique to that system.

The role of a gamemaster in an online game is to enforce the game's rules and provide general customer service. Also, unlike gamemasters in traditional role-playing games, gamemasters for online games in some cases are paid employees.

In ''Dungeons & Dragons'', gamemasters are called dungeon masters, and in the ''World of Darkness'' games, they are called storytellers.

History and variants of the term

The term ''gamemaster'' and the role associated with it could be found in the postal gaming hobby. In typical play-by-mail games, players control armies or civilizations and mail their chosen actions to the GM. The GM then mails the updated game state to all players on a regular basis. Usage in a wargaming context includes Guidon Games 1973 ruleset, ''Ironclad''.

In a role-playing game context, it was first used by Dave Arneson while developing his game '' Blackmoor'' in 1971, although the first usage in print may have been '' Chivalry & Sorcery''.

Each gaming system has its own name for the role of the gamemaster, such as "judge", "narrator", "referee", "director", or "storyteller", and these terms not only describe the role of the gamemaster in general but also help define how the game is intended to be run. For example, the Storyteller System used in White Wolf Game Studio's storytelling games calls its GM the "storyteller", while the rules- and setting-focused ''Marvel Super Heroes'' role-playing game calls its GM the "judge". The cartoon inspired role-playing game '' Toon'' calls its GM the "animator". A few games apply system- or setting-specific flavorful names to the GM, such as the Keeper of Arcane Lore (in '' Call of Cthulhu''), the Hollyhock God (''Nobilis'', in which the hollyhock represents vanity), or the most famous of such terms, the " Dungeon Master" (or "DM") in ''Dungeons & Dragons''.

In traditional table-top role-playing games

The gamemaster prepares the game session for the players and the characters they play (known as player characters or PCs), describes the events taking place and decides on the outcomes of players' decisions. The gamemaster also keeps track of non-player characters (NPCs) and random encounters, as well as of the general state of the game world. The game session (or "adventure") can be metaphorically described as a play, in which the players are the lead actors, and the GM provides the stage, the scenery, the basic plot on which the improvisational script is built, as well as all the bit parts and supporting characters. Gamemasters can also be in charge of RPG board games making the events and setting challenges.

GMs may choose to run a game based on a published game world, with the maps and history already in place; such game worlds often have pre-written adventures. Alternatively, the GM may build their own world and script their own adventures.

A good gamemaster draws the players into the adventure, making it enjoyable for everyone. Good gamemasters have quick minds, sharp wits, and rich imaginations. Gamemasters must also maintain game balance: hideously overpowered monsters ''or'' players are no fun. It was noted, in 1997, that those who favor their left-brain such as skilled code writers usually do not make it in the ethereal gamemaster world of storytelling and verse.

The four major "hats"

* Author: The GM plans out (in the loosest sense) the plot of the story of which the player characters will become heroes (or villains, or rich, etc.); creating (or adapting, or just choosing) the setting, populating that region with villains and other NPCs, and assigning them any necessary backgrounds, motivations, plans and resources.
* Director: During the game, while each of the other players typically controls the actions of one of the player characters, the GM decides the actions of all the NPCs as they are needed. The GM may also direct a particular "NPC" that travels with the party (commonly known as a GMPC), but this may occasionally be open to abuse since the Game Master having a "pet" NPC may compromise their neutrality.
* Referee: In most tabletop RPGs, the rules are supplied to resolve conflicting situations (avoiding the "Bang! you're dead!"/"No, you missed!" quandary). The GM is expected to provide any necessary interpretation of those rules in fuzzier situations. The GM may also approve or provide House Rules in order to cover these corner cases or provide a different gaming experience.
* Manager: The least officially prescribed portion of GMing, and thus the part that takes people the most by surprise. The GM is typically the one to organize the game in the first place, find players, schedule sessions, and figure out a place to play, as well as acting as a mediator and having to balance the needs and desires of all participants—sometimes having to divine the real desires of indecisive or inexperienced players.

In online games

In early virtual worlds gamemasters served as a moderator or administrator; in
