This is the most ambitious narrative in any video game. The amount of effort that must have went into creating this masterpiece is unfathomable. It is not only one of the best stories in gaming (probably #1), but also one of the best sci-fi stories in general that were released in recent years.

There is unbelievable virtiosity with which these characters were all written to be distinct from each other, to parody or reference a certain manga/shoujo/scifi/game trope, for each of them to be an enjoyable story on their own, and to weave all 13 on them together into a grander fantastic sci-fi narrative. The music is as good as it gets, and the strategy elements aren't nearly as boring as it may seem, with a particular incredible moment involving a certain idol song enabled by said gameplay.

This is undoubtedly a classic for the ages. This is a game people in thirty years will point towards when it comes to "video games as a storytelling medium".
