Why Should Game Stories Make Sense?
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.'"
They don't need to make sense in a universal fashion, they can be completely unrealistic/unbelievable. However they should make sense internally. Whatever rules are laid out in the game universe, it should make sense within that setting.
Most people can easily suspend disbelief and accept another world. However that suspension can be shattered if nothing makes sense, the rules keep changing, and there's no internal consistency.
That was, for example, one of the big problems in the Mass Effect games. I won't go in to details to not spoil it but the ending of the trilogy was bad in a large part because it had no internal consistency. It didn't make sense in regards to the narrative that had been going on in the games up to that point. It was a deus ex machinia kind of event that just shattered the story for many.
So no game stories don't need to make sense in terms of the real world, but if they are to be good they should make sense in terms of themselves.
