Andrew Plotkin (born May 15, 1970), also known as Zarf, is a central figure in the modern interactive fiction (IF) community. Having both written a number of award-winning games and developed a range of new file formats, interpreters, and other utilities for the design, production, and running of IF games, Plotkin is widely recognised for both his creative and his technical contributions to the homebrew IF scene.
Plotkin was one of the earliest writers to use Graham Nelson's Inform development system, and one of the first since Infocom's heyday to explore the boundaries of interactive fiction as an artistic medium. Many later authors cite him as a primary influence. He has won many awards within the community, and is frequently interviewed for magazine articles about interactive fiction.
Plotkin has also made major technical contributions to the interactive fiction medium, designing the Blorb archive format, the Glk I/O platform, and the Glulx virtual machine, and implementing Glulx Inform and several interactive fiction interpreters for the Macintosh and X. The Glk API has made possible the creation of "universal translator" interpreters such as Gargoyle, a single program capable of running all interactive fiction formats.

More recently, he was featured on CNN Money for successfully raising over $31,000 using Kickstarter for development of a new interactive fiction piece called Hadean Lands for the iPhone and release of the resulting iPhone game framework as open source.  Plotkin was also featured prominently in the 2010 interactive fiction documentary, GET LAMP.
He also wrote the former shareware puzzle game System's Twilight. Plotkin appears as a character in Being Andrew Plotkin, an interactive fiction game by J. Robinson Wheeler somewhat based on the film Being John Malkovich.
While a student at Carnegie Mellon University, Zarf was one of the early members of the Carnegie Mellon KGB. He created the organization's signature Capture the Flag with Stuff  game, which is now played by several hundred students every semester.
In 1997, Plotkin developed a rethemed version of Dimitry Davidoff's social game Mafia, replacing the "mafia" characters with werewolves. Plotkin's version of the game subsequently became popular at universities and conferences in the United States, with a set of cards being produced by Looney Labs.
He has also made contributions to the Icehouse community, both in designing the game Branches, Twigs, & Thorns and the creation of several custom sets of pieces. During 2006 he was involved in the open source on-line game platform Volity and has created, or assisted in the creation of, on-line versions of the pyramid game Treehouse and other Looney Labs titles to showcase the platform.
