FFVIII is definitely my favorite. It was my first since FF1 and Mystic Quest, meaning it was my first in about 5 years. It had me hooked all over again.

The music was amazing, great battle system, it had a much more serious feel to it. The extra GF sidequests, like Bahamut, the Ultima Weapon fight were awesome sidequests, and the card game was great, although it pales in comparison to blitzball, but that's must me being a sports nut

FFX is a close second. I agree with everything that Abominatrix said on this one. The only kicker, like she mentioned, is that the ultimate weapons aquisition was incredibally annoying. I was ready to gauge my eyes out after about 2 hours of getting a 0.2 sec time on the stupid Chocobo racing

But the extra's like Omega Dungeon, Blitzball, and extra Aeons was awesome. Great character development, great environment, and realistic personalities.
