I don't see how it would ruin the story. Aside from the fact that it would seriously freak out half the fans of the game. Secondly, if they had to remove anything, even something that large, while dubbing, a few text changes and scene cuts could easily do so. There's been a lot of very big changes done when games and anime are brought to America, because we arent as open a society as Japan, and as a whole we generally associate cartoons and video games with children.
