These games are held back by the lack of character bonds and interactions.
I just got into the Octopath Traveler games, and for the most part, I am enjoying them. The characters are unique, and their individual narratives are interesting enough, but I find that the lack of interaction between them is a real hinderance. I am used to those kinds of interactions in games like Bravely Default, Fire Emblem, and Triangle Strategy, where the party is on a shared journey and you get to watch the characters develop alongside one another. It feels odd that Octopath is so narratively driven, has the characters travel in the same party, and yet gives them so few meaningful conversations beyond occasional fluff. It feels like if The Lord of the Rings had their characters travel together and just stonewall each other.
