Since 1995, writers have created computer-based interactive fiction stories for an annual competition--space operas, medieval quests, and countless other adventures that allow the reader to guide the plot.

Here's a short introduction to the genre: "In interactive fiction you play the main character. You type commands which determine the actions of the character and the flow of the story. Each piece of interactive fiction presents locations, items, characters and events. You move about, exploring and learning. As you do so, you will encounter puzzles which impede your progress. Part of the fun of interactive fiction is solving these puzzles."

Check out this GalleyCat editor's favorite pieces from last year's contest: "Everybody Dies" by Jim Munroe and "Violet" by Jeremy Freese. If the digital book-friendly medium makes you excited, you can help judge the 2009 competition. Download this year's interactive games on this page. After you've played five or more games, follow this link to vote for your favorites. Votes are due by November 15th, 2009. (Via Post Position)
