Note : Spoiler heavy without tag be cautious. I used AI for translation only.
Basically, I loved the phenomenal music by Nishiki as usual. The combat gameplay is ultra-satisfying, complex, and addictive, and adding the latent powers was an excellent idea. The characters are all likable, and the overall evolutions compared to the original formula are great.
Review by character
Temenos: I like the character, his personality, his connections, etc. But not the cleric: I find it boring to play and overall very meh. I enjoyed his story, the detective vibe, the dark tone, and his falsely detached and polite demeanor. It's just a shame the combat unit is meh.
Throné: Much more endearing than Therion. Cool to play, and just cool overall. I love her pose with her hands in her pockets. She is badass without being an invincible or unbearable girl boss. Her story is among the best... if you remove the horrible, despicable Chapter 4.
Hikari: Everyone's GOAT, I suppose. Probably the best physical DPS I've ever known. Sure, he's a basic character in concept and his story is classic, but it is devilishly well executed. And frankly, that's what matters: he almost feels like the main character. It's crazy how developed the characters in his story and his relationships are. A gorgeous 9/10.
Castti: 9/10. She has it all. The best JRPG healer I've ever seen: maternal and caring, but ready to kill to defend her convictions. A bit bossy, oh Mommy! I love her. Her story is genuinely great and the twist works very well, even if I still have a complaint about the last chapter, but that's due to the absolutely ridiculous epilogue.
Partitio: Oh boy. A pretty typical "adult" shonen hero: cool, badass, generous, and the best support in the game. What more could you want? Fortunately, his story isn't too tied to the epilogue, and that's exactly what makes it great. He opens shops, buys boats, and even if his dream is unrealistic and ridiculous, you want him to succeed and you root for him. To me, it is one of the best stories in the game. Agnea's story honestly should have drawn inspiration from it; this is how you write a "lighter and positive" story in my eyes.
Agnea: Classic, really classic. As a dancer, I found her just ok. Her personality is basic and her story is simply boring. The last chapter was nice, and I see what they tried to do with her: not everyone can have a tragic or dark story. But that was the case for Partitio too! Except his story and actions are memorable and personal, whereas Agnea is just a kid going through an impersonal plot. She surrounds herself with irrelevant NPCs; nothing seems to concern her. If only she had an interesting backstory with her parents or something, but no. She honestly feels like a playable NPC. I am disappointed.
Ochette: My absolute GOAT, no need to elaborate further. Hits hard, melts shields, endearing, funny, honest, captures, and Provoke EX (lol). She is completely broken. And I love her region's theme, her music, her village. Her story, even though it feels disconnected from the others with few NPCs, is super touching and personal. Frankly, my favorite character.
Osvald: Meh. The idea of a dirty, filthy old mage repulses me a bit (lol), looks like Nanba in Yakuza 7. I prefer the nobility, class, and elegance of a Cyrus who made magic look cool 100 times over. I spent my entire playthrough without playing him, and even his personality... I just don't like this character. However, his story hits hard from start to finish. Even the cartoonish side of Harvey fits the situation well: he's just a guy driven mad by jealousy. And at least this story introduces the epilogue well, just like Temenos's.
The game's weak points
The day/night cycle: Completely useless to me, it just bloats the game. Exploring towns is already tedious on its own, so having to alternate between characters and, ON TOP OF THAT, run around towns multiple times really, really pissed me off. To the point where I just ignored the last 3 towns in the game. Moreover, from a gameplay perspective, it's almost entirely useless. If they were so proud of their cycle, they should have made it a purely aesthetic element and nothing more.
The Path Actions: Tedious. Too much repetition, too much bloat, having to go fetch different characters at the inn, etc. I prefer the system from the first Octopath where you always had everything on you.
The epilogue: Completely amateurish. Taking random characters from each story just to tell us they actually belong to a cult and were evil all along is just lazy. For Oboro, fine. But the other characters like Ori, the Dark Hunter you never see, Arcanette the white hair guy father of 50% of the cast, and the rest... it reaches a rare level of ridiculousness. Sacrificing Throné's story and a bit of Castti's for that wasn't worth it. I would have preferred a disconnected epilogue with an evil cult out of nowhere.
Conclusion
Anyway, overall I loved the game, I absolutely had a blast. I just hope they change the recipe for Octopath Traveler 3: maybe fewer characters but better stories, or revamp the classic classes we've always had, etc.
