Implementer was originally the self-given name of the creators of the
Infocom text adventure series
Zork.
Implementor, often shortened to
Imp, became the title given to game designers and programmers at Infocom. Implementers were inserted as minor characters in several Infocom games. The game
Beyond Zork also includes a group of characters called Implementors, minor deities who are integral to the plot. The term carried over into
MUDs, particularly
DikuMUDs, where it usually refers to a game's owner or owners, similarly to the term "
God".
