This game, man. It has one of the worst middle cases ever, but knocks it out of the park with it's final case. It's a nice bowtie (for now) on the legacy of people, their parental figures, and how it effects their children. And how they get to choose what to do with it. The character dynamics are great in this game, seriously one of the best in the series. A bit of a pain to get through, but it's well worth it.
Play the DS version and gun for the bad ending for a funny translation error.
