Maybe I'm alone in this, but I've soured a lot on FFX over the years. I loved it at launch and played through it a couple times, loved FFX-2, and eagerly bought the ports on PS3, Vita, PS4, and PC...but I just don't really like playing it.
The environment designs feel super dated, the minigames are fucking awful, the music is inconsistent, the voice acting is (understandably) mediocre, and even the gameplay feels super rote (use character X for enemy Y, every time) now that SMT has been hammering the same weakness-heavy turn-based stuff for 15 years since.
I still like the story and characters well enough.
I mean, I don't hate it, and I would certainly place it in the top 100 somewhere, but that's largely because there's a ton on this list I wouldn't have put there, and a bunch I would have.
