On its own, this is pretty straight-forward: There are side quests in Chapter 3, Chapter 8, Chapter 9 and Chapter 14, and for the most part, completing them is just a matter of… well, not skipping ahead to the next chapter when they’re available. In every case, the game will warn you when you’re about to cross the point of no return and advance the story.
Whether you want to complete every side quest in a given playthrough is another matter, as the trophy Dressed to the Nines will require you to purposefully skip some side quests, but for this trophy the only tricky bit is in Chapter 9. There are five side quests in Chapter 9, and depending on some choices you make throughout that chapter you’ll get different quests from different characters. One quest, Burning Thighs is universal, but The Party Never Stops and A Dynamite Body are exclusive to Chocobo Sam, while The Price of Thievery and Shears’ Counterattack are exclusive to Madam M. You can only do three of these five quests in a single playthrough, so you’ll need to come back to Chapter 9 after beating the game via Chapter Select to complete the other two.
Below you’ll find a list of the events in Wall Market (Chapter 9) that influence what quests you’ll get, and what you need to say or do to get them:
|Event||Chocobo Sam Response||Madam M Response|
|First talk with Chocobo Sam: “The girl we’re looking for…”||She’s in great shape.||She’s a great fighter.|
|Talk to the guy outside the hotel: “Stay the night?”||…No, thanks.||How much?|
|Vagabond Johnny (talk to Johnny near the Honeybee Inn)||Yeah.||No.|
|Second talk with Chocobo Sam: “Heads or tails?”||Heads.||Tails.|
|Talking to Madam M: “Choose which course?”||Poor Man’s Course - 100 G||Luxury Course - 3000 G|
|Talking to Madam M: “How is Aerith’s outfit?”||It’s alright.||Looks comfortable.|
