Even though FF5 had my favorite battle system, I still prefer the system of fixed character classes. That gives them more individuality, and IMHO, it was best used in FF9, FF4 and SD3. I don't like having a big group where everyone is a clone of each other like in *cough* FF8 *cough*.

By the way...

What do you like more? The customizable character games (2,3,5,7,8,10,T) or the fixed character games (1,2,4,6,9)?
How can FF2 be in both of the types?
