The next year, Clare and I prototyped an authoring system for writers of card-based fictions. It has since disappeared in a hard drive crash.
At the time, card-based storytelling was very popular with writers.
- Robert Cover wrote Heart Suit
- MouseChief was working on The Witch's Yarn
- Mark Bernstein had been writing about Card Shark and Thespis
In 2008, Penguin published "The (Former) General In His Labyrinth" by Mohsin Hamid
If you want to write one now, I would suggest Undum: A client-side framework for hypertext interactive fiction games.
