Photopia
Photopia is a piece of literature by Adam Cadre rendered in the form of interactive fiction, and written in Inform. It won first place in the 1998 Interactive Fiction Competition. It is effective in part because it subverts the expectation that one has upon encountering a piece of interactive fiction: that your actions will have consequences. Photopia is puzzle-less and linear, allowing the player no way to alter the eventual conclusion while maintaining the illusion of of non-linearity. This gives horrendous and deeply felt weight to some of the story's motifs -- questions of free will and determinism.While Photopia is not a true example of puzzleless interactive fiction, it is regarded as a pioneer in narrative-oriented, rather than puzzle- or challenge- driven IF, and is perhaps the most successful of this genre to date.
