Thought for the day: Story

While Dragon Age offers choices in dialogue which will lead to minor variations in the story, ultimately all these variations lead back to one main story line, which never changes. If I were to play through the game a second time, the same major plot elements would happen, and there would be nothing I could do about lets say getting betrayed a second time. While better storytelling especially in MMORPGs would be nice, it all ends up with us being trapped inescapably in stories we already know. Is story the death of replayability?
