FFI - Disliked (More meh towards) - The introduction of the series, the job classes, etc. The latter games exist because of this game. Also that Garland shall knock us all down.

FFII - Disliked (Meh, also) - The keyword system I loved and being able to customize my characters to a good extent.

FFIII - Liked (ish) - The difficulty of it. Not the most approachable FF, so a lot of my replays end up abandoned.

FFIV - Liked - The dungeons were much too long and led to many moments of frustration.

FFV - Liked - Some of the versions really miss the mark on what makes FFV so great. They just end up bland and generic.

FFVI - Disliked (closer to a meh, really) - Liked the story and a lot of the characters.

FFVII - Liked - HAAATED Aeris/th with a passion and really didn't like that many characters. The ones I did like are kind of meh on my overall list of best characters.

FFVIII - Liked (loved) - The Junction system preventing me from using magic was poopoo.

FFIX - Liked (Fav game ever) - Gosh the battle system is sllloooooooow which becomes painfully obvious when there's a timer counting down. Also the Trance system is garbage.

FFX - Liked - Gets kinda boring after a while. Linear in both world and gameplay.

FFX-2 - Liked (loved) - Some of it was just super cringeworthy.

FFXII - Liked - All dat sand and lack of character focus.

FFXIII - Liked (ish) - Gosh that story was a convoluted mess
