Sometimes there are pieces that clearly fall into the category of interactive fiction. Old-school choose-your-own-adventure books, for instance, could be read front to back but little meaning could be gained by it (except in a few rare cases). In the same way, a parser-based game does not continue on unless the player types in commands. The element of choice, agency given to the reader, is not only a part but is essential to the furthering of the story. The reader becomes not just a passive observer, but an actor within the work.
Then there are pieces that are closer to the edge between ordinary literature and interactive fiction. Andrew Hofmann, in his piece Coin Toss, discusses the nature of games and other interactive mediums, questioning whether one’s interpretation and response to any medium provides the level of interaction typically only allotted to games.
