The game is split up into these small chunks of story (at least in the beginning). I'm only 10 hours in, despite getting on release day, as I tend to play just one scenario per day (if that). So far I'm really enjoying it's mechanics. Each class is vastly different from the others, more-so than most other games.
My favorite thing about Octopath is the atmosphere. Seeing real-time lighting and shadows cast from 2D pixel art. I do play with the vignetting enabled, but I can't point my finger on what exactly I like about it. Each town has it's own lore.
