I call it art.
The gameplay as a whole is really fulfilling; its just exciting boss battle after boss battle which everyone loves and has me wondering why no other game like this has been released before. Even after beating it i kept coming back to do Time Attack and Hard Mode because the battles are just so much fun. The story is beautiful, just don't expect a lot of words, its the overall feeling the game focuses on. This feeling flows out of the television screen with brilliant scenery, an inspiring soundtrack, and jaw-dropping scale. Truly a rewarding piece of art for those who can appreciate it.
