well... i'm a sucker for anything to do with a moogle! they are my favorite characters in any of the games (even though you don't really play as them :p)
I love them so much that i've recently bought a moogle mascot costume for the next festival i attend!
I joined the final fantasy world when i was randomly choosing a game to try out at the rental shop. i chose FFX! by the end of the week i'd already spent 45.36 hours on it (kinda wasn't a good idea because of school and all...) and ended up buying it! I've been buying and playing them ever since. i'd say im pretty dedicated to the franchise since i own every game in the series (after many many years of tracking them all down :P)
