I said this earlier in the thread and was directly told that, going off what we know about the production pipeline Square had at the time, it seems that much of the story for IX’s later half wasn’t finished.
Makes sense. I always felt that the game was lopsided to the start and the second half is full of things just… kinda… happening?
It’s sad to think that, possibly, there’s a world where IX got the breathing room it needed in development and we got a story that incorporates the full cast far better. But forgetting cool cast members is somewhat of a staple for FF, isn’t it?
