An anonymous reader writes "An opinion piece at Polygon raises an interesting question about how we perceive video games: why does so much effort go into having the plot make perfect sense? Think about games you've played that have a story. How much do you actually remember? You can probably name the protagonist and antagonist, but do you really know what they were fighting about? The article says, [Developer Jake Elliot] talked about the difference between a puzzle and a mystery. He argued that a puzzle has a solution, while a mystery may never be solved. A puzzle must make sense, but a mystery may well not. In the context of a game, the mechanics are the puzzle, while the theme is the mystery. The game play must be predictable, or the player will never master it. But the theme can be evocative and open-ended. A theme evokes the horrors of war; the mechanics remind you to reload your gun. The plot is stuck in the middle. It wants to make sense of a game, but the game play is already doing that. If we were watching a movie, the plot would provide the backbone, but games don't work like movies, and the plot can get in the way. It can feel awkward and unwelcome, while a looser thematic layer can be the most memorable part of the game.'"
