I am a fan of most final fantasy games, 10 and 7 being my personal favourites (if you wanted to judge my standards).
I was quite worried that this game wouldn't be that good, but I couldn't have been more suprised! I like that you can switch between lots of characters with different abilities, also, when you buy armour and helmets etc, you can actually see them on the characters, which lets you customise them more and also there's a couple of really good costumes. AND.. there is a little moogle (if you like that kind of thing) which you can customise too!
Definately buy this game if you like cute stuff, cos it's full of it. But there's also alot of good game play to dig into.
