After playing the prologue demo and having read bits and pieces from the previews and media buzz around the game up to this point, I get the sense that the OctoTrav hype base has taken the few scattered comments about "there is a main story" and interpreted that in a way that probably isn't nearly as accurate as people's dreams of the game have envisioned. The way the game is designed kind of necessitates that the game doesn't at some point turn into "eight heroes band together to [accomplish whatever task] in one big glorious opus once you get their introductory things out of the way." I suspect instead that the main story being referred to by the developers isn't a singular grand narrative, but more like a big puzzle wherein each of the eight protagonist's individual stories lend a few pieces. One character may encounter an antagonist during their storyline whose motives are more fully hinted at in someone else's, for instance. That way every character still goes through their own personal arc, but the party interactions and sense of larger story comes from the more subtle ways in which those individual tales weave around each other. Less of a singular plot and more about world-building.
If that's the case, then it's not what a lot of people were expecting, and the FFVI comparison definitely doesn't add up from a story presentation perspective at least, but I still personally find that plenty interesting enough so long as the 8 protagonist's stories are well-told. Still, the clash between the hype train and the anti-hype wall has been curiously strong with this project, and has been for a while now. That's...disappointing.
Man, the review thread for this game is absolutely guaranteed to be a shitshow, isn't it?
