Suggestion: A section with Echo's Quotes (japanese and english), including Outfit-specific ones would be nice. Ideally with playable Audiofiles, but text-only should be ok, too.
This would be a good addition for everyone who joined Mobius FF later and might have missed some Outfits. Maybe it is possible to aqcuire the audiofiles by extracting them from the game itself? Game seems to be written in Unity, so maybe it is possible to inspect those files?
