Yeah i really liked this soundtrack. Up there in the top 3 for sure. Apocalypses Noctis when fighting leviathan is epic.

music: FF8. almost the entire ost is memorable. might sound awkward but if i had to chose itd be the fisherman horizon theme.

character: here i had to think a bit. i chose Tifa from the original FF7 because of not breaking clouds delusional bubble and playing along until kalm. That takes quite some empathy and sensitivity considering they were childhood friends with now alternate memories.

о чем вы говорите

FFXV is my favourite soundtrack, because the highs are extremely high, although I don't much care for the music for the cities and towns - I like FFIX's soundtrack for how each of its many locations has a very good theme.
I can't really choose a favourite character in the series, there's so many I adore! My favourite in FFXV is Ignis. I also love Vivi, Garnet, Zidane, Auron, Balthier, Aerith, Tifa, Zack and Cloud, I've yet to play VI, but I know I'll love Terra.

FFXV has an amazing soundtrack. I still listen to some tracks whenever i drive. Nvidia, or somnus being noticeable first picks for me. I feel like just listening to the ost you can get a feel for the game.

FFX. FFXIII also has an amazing soundtrack, imo, despite the corridor gameplay.
FFXV is amazing too, and a breath of fresh air.
They all made me laugh, made me cry, helped me through difficult times, gave me different taste of styles and locales, and I listened to them regularly over the years.
Character wise, idk. I haven't fully played the old ones before X. I like most of Nomura's character designs generally so I'm going to be spoiled when getting round to FFVIIR.
