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 adventures 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.
The Interactive Fiction Competition is one of several annual competitions for works of interactive fiction. It has been held since 1995. It is intended for fairly short games, as judges are only allowed to spend two hours playing a game before deciding how many points to award it. The competition has been described as the "Super Bowl" of interactive fiction.

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.

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.
