Alright I'll give it a shot.
BASICS
I am a: Male
My age is: 20-25

INTRODUCING
What was the first FF game you played?
Final Fantasy VII as it was the first Final Fantasy game to arrive in Europe.
How old were you started play FF?
10 years old. (Though my brother played it mostly with me watching)
Who or how did you get introduced to the world of FF
My brother did. A funny background story: Back on the old ps1 you had these demo discs. There were playable games and there were video's. When I thought of demo's I thought of the playable games. However on the first demo disc there was a movie of FF VII. My brother said he was going to buy it and I was completely against the idea because being 10 years old, I thought it was just a cd with a movie on it.

FAVORITES
Favorite FF of all time?
Final Fantasy IX
Name your favorite summon/Eidolon/Esper/GF?
Shiva. Breasts, Feminine, need I say more? Yes beastly instincts. =P Though I'd choose chocobo for the funny factor and Knight of the Round Table for damage. Siren is also a very pretty summon. Oh and Odin is awesome for the instant death factor. Yojimbo was a hilarious summon to have the times I got away with 3x or 4x zanmato and almost beated the dark summons in FF X. As you can see I can't pick!
What game has the best level system?
(Example: Materia, Sphere grid, License board?
I'd have prefered the term battle system here. But let's see. I'd have to say FF IV when it comes to truly the leveling system. But the materia system was very well done. (the GF was nice but you could kind of cheat your way through it via the cards and still see no benefits as the monsters just grew along with you.
Favorite male character? (playable)
Oh this is a hard one. I'll just pick three. Locke for his compassion, loyalty and humor. Cyan for having the strength to lose his whole family and castle and still keep on going! Steiner because he's really a funny and stubborn knight but even with a big mouth, he has a gentle heart.
Favorite female character? (playable)
Aeris. I know it's a cliche, but I do. As for the character, not for the playability, which for some mysterious reason doesn't let you play her all that long.
Favorite bad guy?
Favourite bad guy, well, that's a tricky one as well. For best bad guy it would be Sephiroth. He has a human spirit yet he is completely insane and evil. But when it comes to the word favourite, I think of what bad guy I actually didnt feel too bad on with grudges and such. Then I'd have to say Kuja.
Favorite optional boss?
Hmm optional bosses. Ultima Weapon from FF X. (not underwater weapon from FF VII. He creeped the shit out of me)
ENDING
What FF game has the most interesting story?
Final Fantasy VII. Definately
What was the first FF game you finished?
Final Fantasy VII but if I'd have to say ALL by myself, without any help from anyone else, it would be FF X.
What FF game gave you the most challenge?
Hahaha, I instantly think of FF II. It's such a pain in the ass that it's not even a challenge anymore. I never beat it. I remember not being able to beat Sephiroth at lvl 65. Then we lvled to 99. But truthfully Final Fantasy VI. It gave me a lot of challenges and side quests to do.
What FF game from V and forward would you like to see a remake of?
Final Fantasy VI. Because I can know they could make it very beautiful, or even a movie of it. No I am not that fond of having a remake. Which is teh exact reason why I am against a Final Fantasy VII remake. They made it so good back then that a remake would destroy the atmosphere.
There I put my two stones in. =] Thank you for reading!
