A train might seem like the worst metaphor possible for a video game. We are often reminded (or at least often hope) that what makes video games different from other artistic mediums, like novels, films, or music, is their ability to tell a different kind of story. We talk a great deal about player choice, divergent paths as a result, and the possibilities of a multilinear experience. Quite the opposite of a train (or most novels, films, and music), the video game affords the opportunity for branching paths and different resulting conclusions. Indeed, if a game is “on rails,” this usually isn’t considered a positive—at least from the perspective of narrative progression.
