This game is a culmination of everything that I love about the mechanics of this series, with a story that rides off the ending of the previous game into a crescendo that continues to grow until the very end.
This is one of the few game worlds that really motivates me to seek out everything that it has to offer, even down to being regularly updated on every NPC's life and reaction to events. People praise this series for its worldbuilding and I'd always shrugged that off as something not really all that important, but the amount of detail that goes into breathing life into your surroundings is a huge part of what makes Crossbell such a charming setting. It almost makes me feel bad to leave it, and yet this game did such a good job of setting up for the following games that I can't help but be excited for them. But regardless of how I end up feeling about the rest of this series, I'm very grateful that I made it to this point.
This is about as perfect as a game can get at achieving everything that I love about this medium.
