It's true that games have typically not been great vehicles for storytelling, but it is understandably so. In a movie, the story is the main element that engages the viewer with visual presentation and music following it closely. In a videogame it's the gameplay that engages the gamer, and story is purely secondary. Tetris didn't need a story and the story only got in the way of every Mario Bros. game. Games can have a story, but since the story only serves as a motivation to keep the gamer playing the game, most developers so far have only made them barely adequate. A game might come along with a great story that is not riddled with cliches, but if it controls like sit, nobody will buy it. So anyone making a game will first and foremost pay attention most to the mechanics, then the grpahical presentation, and then the story.
