LEAST FAVOURITE GAME: II, XII

BEST HERO: The only one of the FF heroes who cleansed himself of his dark past by learning the importance of Justice and Mercy (a life lesson I carry with me to this very day): Cecil.

BEST HEROINE: Aeries: She was the deciding factor of everything that happened at the end of FFVII.

BEST VILLAIN: Zeromus, the living embodiment of the collective hatred of all living beings.

BEST SUPPORTING MALE: GOGO!! Not only could he mimic some awesome spells, but he had the sweetest home security system featuring leprechauns in tuxedos and the absolute BEST theme song!

BEST SUPPORTING FEMALE: I'd like to give it to the Magus sisters, but I don't think they count. Yuna, then, for summoning them, for a strength of character that didn't interfere with her sweetness, her wisdom, and most of all, for those damage-raining summons in her repitoire!

BEST BATTLE THEME: The original ff battle theme was okay. 6's was awesome. 7's lost me with the synth guitars. I can't give it to 12 because the music stayed the same. The one that resonates with me the most to this day is 4.

BEST WINNING THEME: Definitely VI.

BEST BOSS THEME: There's no topping Gilgamesh.

BEST SUMMON: Anima.

BEST BATTLE SYSTEM: ANY of them except that accursed 13!!

BEST DEVELOPMENT SYSTEM: I was kind of partial to the automatic system of the early games until X came around. I have to say X now.

BEST STORY: X

BEST AIRSHIP: I might have many people disagree with me, but I was always partial to the Ragnarok of VIII. Partially because of the name, partially because of the look. However, I now have to give it to XII. The Strahl.

BEST SETTING: I know some will disagree and I may face death or expulsion from the site for this... I give it to XII.

WHICH IS THE DARKEST: I give that honor to VI. How much darker can you get than to be witness to the end of the world?

WHICH IS THE LIGHTEST: XII. The only real danger is the threat of war. Ooooooh!

BEST LOOKING CHARACTER: I've always kinda had a thing for Yuna.

BEST CID: Viscious. Kidding. Highwind. (VII)

BEST BOSS: Orphan for looks, Emerald Weapon for difficulty.

BEST LIMIT BREAK SYSTEM: VII:

BEST SCORE: Interlude.

BEST SONG: Dancing Mad. Period. One Winged Angel is a distant second.

BEST MINI-GAME: Blitzball, after I figured out how to be good at it.

WORST VILLAIN: Siegfried (FFVI): What the...?!

WORST CHARACTER: Hope, FFXIII. I'm embarassed for little kids his age everywhere.

BEST ENDING: I gotta give it to VII.

FAVOURITE GAME: VI, IV, VII IN THAT ORDER.

LEAST FAVOURITE GAME: XIII and VIII
