“Interactive fiction tells you the beginning of a story. Then it puts you in charge and lets you decide what your character should do. You type commands for the main character to carry out, and the story replies by telling you what happens next.”.
“If you enjoy interactive fiction, you’ll find a wide variety of other works available to you. And, like books, works of interactive fiction come in assortment of genres: fantasy, mystery, horror, and science-fiction, romance and historical, surreal and slice-of-life. See my PDF Manual on playing IF.”. (Emily Short)

“A Tron clone in 3D.
This has been the tagline of Armagetron, since, well, a very long time, and is probably the shortest and most accurate description possible.”.

“Tron was an arcade game based on the movie of the same name, released by Disney in 1982.
The player uses a left/right joystick to control a Light Cycle which leaves a wall behind it wherever the cycle it goes, turning only at 90 degree angles.
The player must then get the AI to crash into their wall while avoiding hitting the AI’s own wall themselves.”.
