Third, you should add Mystic Quest to your FF lineup, its a half decent game and Curtain Call canonized it.
More like it recognized its existence because the sountrack is fairly decent.
Also, you should totally count Dirge of Cerberus in your Final Fantasy list because, whether you or anyone else likes it or not, its still a part of that awful FFVII compilation, and you can't skip out on that one if you're including every other ill-conceived Squeenix compilation title. Also also, you should add Advent Children to that list (just hold a controller in your hand, hold forward, and occasionally tap the X/O/B/A/confirm/deselect button and you can easily write it off as a full fledged Squeenix videogame).
Fanbase shenanigans aside.
VII alone is very much isolated from the Compilation and that same Compilation, at the same time, its is own thing that uses VII as a basis to keep expanding itself.
