He is not talking about stories themselves (as in wether or not a game a deep story), he is talking from a designers point of view. He is talking about the way they are presented, some designers are presenting it like a movie. Basically, you becomes a spectator rather then the player, that a big difference in other medias vs games. He is doesn't like that designers are trying to be like directors making their games more like movies. He said the player should be the director. There is a difference showing it to you versus letting you experience it.
