{{main|Gamemaster}}
One common feature of many RPGs is the role of a gamemaster (GM), a participant who has special duties to present the fictional setting, arbitrate the results of character actions, and maintain the narrative flow.<ref>(Tychsen et al. 2005:215–216) "The areas for which a GM can be responsible, regardless of the game platform (PnP RPG, LARP, CRPG or MMOG), vary not only internally in games from each platform but also across platforms. A GM in an MMOG generally has different responsibilities than a GM in a PnP RPG. These differences can be related to a limited number of variables, such as the media of expression. In some tabletop role-playing games, including Dungeons and Dragons, the GM is referred to as the Dungeon Master or DM. The full range of possible responsibilities of GMs can be subdivided into the following five categories, which also cover the functions of automated storytelling engines: [Narrative flow, Rules, Engagement, Environment, Virtual world:]"</ref> In tabletop and live-action RPGs the GM performs these duties in person. In video RPGs, many of the functions of a GM are fulfilled by the [[game engine]]. However, some multi-player video RPGs also allow for a participant to take on a GM role through a visual interface called a ''GM toolkit'', albeit with abilities limited by the available technology.<ref>(Tychsen et al. 2006:255) "In a computer RPG, the role of the GM is taken on (with varying degrees of success) by software."</ref><ref>(Tychsen et al. 2005:218) "CRPGs can be separated into ... those few who have incorporated a GM toolkit instead of a fully automated storytelling engine. ... In PnP RPGs and LARPs all lines of normal human communication are available: Speech, Emotion and Body Language (Figure 3). In CRPGs and MMOGs, they become narrowed down due to technical limitations, albeit with the added feature of Scripting as a means of communication. Additionally, contemporary game engines do not allow for on-the-fly updating of the game world and generation of new content in reaction to the actions of the player-controlled avatars (or characters in PnP RPG terminology)."</ref>
