"Usually the story in a video game uses the same techniques found in other mediums. Epic adventures that have clear beginnings and ends. No matter what sort of free-roaming choices there might be along the way, games tend to follow a linear series of events that lead the protagonist to The End. Games might have multiple ending depending on player choices, but each run through a game is a self-contained journey with its own neat conclusion. The game 9 Hours, 9 Persons, 9 Doors uses a format that can’t be done in another medium; each trip through it will result in a decisive end, but all of these journeys combine into a single cohesive tale."
