Interactive fiction is a genre of storytelling that allows readers to participate in the narrative. Unlike traditional books, where the story is fixed, interactive fiction often presents choices that influence the direction and outcome of the plot. This format can be found in various media, including video games and text-based adventures. Players typically navigate through a story by making decisions at key points, which can lead to multiple endings. Popular examples of interactive fiction include Zork, a classic text adventure game, and Twine, a tool for creating branching narratives. This engaging format encourages creativity and exploration.
