Dunno, I've been to Japan multiple times and love Kurosawa movies, but I just didn't give a single shit about this story. It was very much "your princess is in another castle" scenarios and then the ending.
The "honorable" intentions thing they tried to go for fell flat because if you don't use those tools to play you are essentially denying yourself half the gameplay element. It wasn't like 47 Ronin or Seven Samurai in how it built any of the characters in anyway more than a superfluous way. Its like they tried to emulate what Witcher 3 did without understanding why all those side quests were so beloved.
I do think it's Sucker Punch's best game to date and I've enjoyed all of them they've released and I look forward to seeing what they do next. But the story of this game is flat and predictable as hell.
Maybe you just didn't feel it but I thought everything was paced really well, chapter one was titled 'Rescue Lord Shimura' , the aim and outcome was clear...
The character stories seemed to be unique, memorable and fitting.... particularly Masakos, Ichikawa and Yunas.... I was a bit colder on the monks, even though it wasn't bad it just seemed less unique.
Mystic tales were awesome .... I loved those.
I thought the twist late in chapter 2 was great and the ending and prologue were fantastic and memorable... very cathartic and emotional respectively.
So I really don't understand the point about 'your princess is in another castle'
I liked that the areas you were introduced to looked very different too and more verticality was introduced in later areas.
Duels were epic too, one of my favorite parts of the game.
I found it much more engaging than Watcher 3 due to the far more engaging gameplay / combat, more vibrant world that seems more alive and the antagonist was way more memorable.... it's also more grounded and doesn't depend on fantasy tropes like Witcher... much of the Elvish culture in W3 is just a load of random Irish word thrown together and stories from Irish folklore 'borrowed' without any reference or thanks.
Anyway the game seems to be extremely popular, with amazing word of mouth.... here is a music video I just watched...
