1 - Squall Leonheart - Probably sentimental value more than anything else as FF8 was my first SE game but I really warmed to Squall and how we seen him develop into a strong leader throughout the story. I enjoyed his relationship with Rinoa too.
2 - Zell Dincht - The most humorous character yet in FF IMO. Kinda felt bad for him at times the way he was picked on by Seifer and the way he was undermined by some of his team despite always doing his best for everyone.
3 - Tidus - People like to pick on Tidus but I thought he was an excellent protagonist and I really got behind him with his struggles of missing home and trying to understand a new world when you had the likes to Wakka telling him to cop on. The voice actor did a great job with him.
4 - Rinoa Heartilly - I don't know why I like her a lot I just do. Seeing her out in space sorta melted me. That FF8 buzz again.
5 - Auron - The GOAT. Great voice actor, sage asf character. Worked well with him being the guy you went to to understand Spira better.
6 - Wakka - Probably a tie with Auron. I liked the cast of FFX a lot.
7 - Basch - A great character in a game that Balthier (ugh). Loved how committed to his homeland and honourable he was.
8 - Lulu - Sexy voice, sexy woman, wise, cool.
9 - Vaan - Vaan is an underrated character with a lot of people I think. Think it's natural to warm to main characters more but I thought he was a refreshing opposite side to a game was very set on being a tale from middle earth.
10 - Steiner - Liked him a lot in FF9 as the loveable oaf.
