God or Goddess, in MUDs, often refers to an administrator of a MUD server, most typically the owner. Sometimes multiple individuals with the title of God are present, or the term may even be applied to all administrative and development staff, but it is usual for the term to refer to the most senior administrator. A similar term, mostly used in DikuMUDs, is implementer, or "imp".
The appearance of entities referred to as "gods" in a MUD does not necessarily mean that this usage of the word is being applied; the word's ordinary usage is also frequently in evidence, referring to non-player character gods or even non-administrative player character gods.
Discussion of MUD Gods frequently touches on the absolute power individuals assuming this title typically have over the virtual environment. A common conflict in MUDs occurs between an administrator who uses this power in an arbitrary and capricious fashion and others who believe standards of fairness should be upheld. MUD-related works often warn prospective players against annoying a God, citing the lack of behavioral constraint on this sort of figure.

"Above players in the MUD hierarchy are wizards, who have gained the highest levels and accomplished all the quests, and are responsible for actually building the MUD environment and administering the MUD. [...] Highest-level wizards are often called Gods and, as the name implies, have near absolute power to implement decisions on their MUDs."

In most MUDs, Wizards are barely distinguishable from Gods—they're barely one step down from the God of the MUD. [...] Gods can do whatever they want to whomever they want whenever they want—it's their MUD."

"[pp. 70] OC, or Out of Character, issues fall under the basic laws governing system administrators everywhere, not just on MUDs. But only on MUDs is it normal for these folks to openly call themselves gods. [pp. 73-74] Elizabeth Reid [...] states: Gods and wizards may be the ultimate power within each MUD universe, and may often be the subject of respect and even fawning [...] The potential for abuse of power and for unfair treatment of players can create resentment, particularly when there is a conflict between individuals who feel that gods and wizards have a duty to behave fairly and those who feel that the administrator of a MUD system has the right to do with it as he or she likes."
