Does anyone else love the presentation of the story? Because of the limited format of text, there's a lot of implication and undercurrents that don't get noticed until you actually beat the game. In that way, it feels like a power metal storyline: the written story is only a few lines per song, with a good portion of the story being represented by the guitar solo, and only when you finish it and go back over it does the meaning of the music become clear.
