Interactive fiction, often abbreviated IF, is software simulating environments in which players use text commands to control characters and influence the environment. Works in this form can be understood as literary narratives, either in the form of Interactive narratives or Interactive narrations. These works can also be understood as a form of video game, either in the form of an adventure game or role-playing game. In common usage, the term refers to text adventures, a type of adventure game where the entire interface can be "text-only", however, graphical text adventure games, where the text is accompanied by graphics still fall under the text adventure category if the main way to interact with the game is by typing text. Some users of the term distinguish between interactive fiction, known as "Puzzle-free", that focuses on narrative, and "text adventures" that focus on puzzles.
Inform is a programming language and design system for interactive fiction originally created in 1993 by Graham Nelson. Inform can generate programs designed for the Z-code or Glulx virtual machines. Versions 1 through 5 were released between 1993 and 1996. Around 1996, Nelson rewrote Inform from first principles to create version 6. Over the following decade, version 6 became reasonably stable and a popular language for writing interactive fiction. In 2006, Nelson released Inform 7, a completely new language based on principles of natural language and a new set of tools based around a book-publishing metaphor.
Text Adventure Development System (TADS) is a prototype-based domain-specific programming language and set of standard libraries for creating interactive fiction (IF) games.
Colossal Cave Adventure is a text-based adventure game, released in 1976 by developer Will Crowther for the PDP-10 mainframe computer. It was expanded upon in 1977 by Don Woods. In the game, the player explores a cave system rumored to be filled with treasure and gold. The game is composed of dozens of locations, and the player moves between these locations and interacts with objects in them by typing one- or two-word commands which are interpreted by the game's natural language input system. The program acts as a narrator, describing the player's location and the results of the player's attempted actions. It is the first well-known example of interactive fiction, as well as the first well-known adventure game, for which it was also the namesake.
Photopia is a piece of literature by Adam Cadre rendered in the form of interactive fiction, and written in Inform. It has received both praise and criticism for its heavy focus on fiction rather than on interactivity. It won first place in the 1998 Interactive Fiction Competition. Photopia has few puzzles and a linear structure, allowing the player no way to alter the eventual conclusion but maintaining the illusion of non-linearity.
Galatea is an interactive fiction video game by Emily Short featuring a modern rendition of the Greek myth of Galatea, the sculpture of a woman that gained life. It took "Best of Show" in the 2000 IF Art Show and won a XYZZY Award for Best Non-Player Character. The game displays an unusually rich approach to non-player character dialogue and diverts from the typical puzzle-solving in interactive fiction: gameplay consists entirely of interacting with a single character in a single room.
The XYZZY Awards are the annual awards given to works of interactive fiction, serving a similar role to the Academy Awards for film. The awards were inaugurated in 1997 by Eileen Mullin, the editor of XYZZYnews. Any game released during the year prior to the award ceremony is eligible for nomination to receive an award. The decision process takes place in two stages: members of the interactive fiction community nominate works within specific categories and sufficiently supported nominations become finalists within those categories. Community members then vote among the finalists, and the game receiving a plurality of votes is given the award in an online ceremony.

His interactive fiction has frequently been nominated for XYZZY Awards and has won on multiple occasions, including Best Game, Best Story and Best Setting awards for All Roads in 2001. Ingold's works are notable for their attention to the levels of knowledge that the player and player character have of the in-game situation, with the effect often depending on a player who understands more than the character or vice versa. Ingold has also written a number of plays, short stories and novels.

An adventure game is a video game genre in which the player assumes the role of a protagonist in an interactive story, driven by exploration and/or puzzle-solving. The genre's focus on story allows it to draw heavily from other narrative-based media, such as literature and film, encompassing a wide variety of genres. Most adventure games are designed for a single player, since the emphasis on story and character makes multiplayer design difficult. Colossal Cave Adventure is identified by Rick Adams as the first such adventure game, first released in 1976, while other notable adventure game series include Zork, King's Quest, Monkey Island, Syberia, and Myst.
