I've always had a soft spot for 13. Yeah, it's very linear (So was X). Other things made up for it imo. Gameplay is extremely fun. Most of the characters are pretty cool. Loved the world(s) and story too. Feels like a legit final fantasy compared to 15.

My favorite might be 9. 7 and 8 right behind it. 6 is definitely a classic and in my top 5 for sure.

Absolutely hate 12. Can't get into it. Zodiac Age only made it worse imo (restrictive license board). 3 is pretty weak and kind of a step back from what they did in 2.
