(Personal) Ranking of Final Fantasy Games
Similar to my Legend of Zelda list, Final Fantasy is another great franchise I've grown up with. (It's also another one I've ranked with ATACS).
This list only includes titles I've played. I'm including sequels (e.g. FFX-2) but not spin-offs (e.g. Legends, Mystic Quest, Mobius, etc.), even though some of those are pretty good games. I haven't played enough of the MMO titles to include them here, though I'm not sure if they would fit on this list anyway.
Update (09/16/2020): Adding FFXII.
I've decided not to include FFXIV for now (though it could be my favorite Final Fantasy). An MMO is a different core experience -- many of the games on this list span generations and gameplay styles, but all are primarily self-contained, single-player experiences.
If I were to make an extended Final Fantasy franchise list, the games I've played now include: Adventure, Legend I, II and III, Mystic Quest, Tactics A2, Mobius, Theatrhythm: Curtain Call, XIV and VII Remake.
