Hey that's cool you're willing to give it another shot!
Likes-
Story-Not much to say other than it's an excellent story.
Visuals-Superb, even still today.
Characters-I can tell you a few seem annoying at first, but they really, really grow on you.
Locations-FFX has some of the best locations-Thunder Plains, Besaid, Omega Ruins, Macalania Woods, etc.,
Side Quests- Very fun and challenging side quests and one very huge one that can eat more than 100 hours.
Weapons- Awesome weapons, and the ability to customize them {there is also "ultimate weapons" for each part member}.
Enemies- Great array of enemies and some of the optional bosses are utterly insane and can take upwards of half an hour to beat. But darn it feels good when you see them fall!
Summons-Best summons in any FF game {in my opinion}.
Sphere Grid- It really is a great system once you understand it.
Dislikes-
Wakka {he is cool, just didn't like his weapon or attacks so never used him}
Blitzball {kinda fun, but too easy to exploit and win every time}.
