Octopath Notes

Story:
General:
Characters should interact more with each other. Currently it feels like 8 separate stories that the other characters are just "there" for. That shouldn't be the case... at all.
Should also limit how linear the story is by having specific items in different character's stories interact with other chapters. Ex: finding a special key in the cave olberic goes that unlocks the gate for a mansion primrose needs to get inside.
Shouldn't force any one character to always be in the party unless it is their chapter specifically. Only exception being possibly chapters 2 and 3 with the required character being in the party at all times during the chapter.

Chapter 1:
Mostly fine, introductions are well done imo and they are winnable even if the character is solo. However, perhaps the addition of an NPC if the story permits one to act as an additional unit, similar to how Prim and Ophilia can add an NPC unit and call on them. Not entirely necessary imo though.

Chapter 2:
Should involve interactions with 1-2 actions independent of the main character's actions (Obtain an item by stealing it or buying it in an Olberic chapter, charm or lead a person in a Tressa chapter, etc) and require some key item obtained in another character's chapter 1. This is to ensure the player has at least 4 characters to utilize but the 4 are not set in stone for each chapter. It also involves other travelers in each others stories without feeling forced interactions.

Chapter 3:
Should involve 1-2 specific characters independent of the main traveler for the chapter. This means both having them more heavily involved in the story as well as their ability being necessary to progress. Should also involve a key item obtained in another traveler's chapter 2, like the previous chapter.

Chapter 4:
Should involve a specific group of 4 characters (the main one for the chapter included. These four should be pivotal in helping the main character complete their story (needing their abilities, using knowledge they would have obtained in their other stories, etc.). Key item is somewhat up in the air for this one, as it's already using other characters.

Finale:
Why is it a hidden mission exactly
