It's most like Final Fantasy V in terms of the story pre divisive twist. Which shouldn't surprise anyone considering that in many way this game is a love letter to FFV , in the same way 4 HoL was to FFIII.
I never got to play 5, after this I might get it to play on the Vita. As for the pattern you note here, I mentioned in my review in the spoiler thread that I would love the next in the series to be a similar love letter to the ps1 era.
