The difficulty of the game depends a lot on the party you choose. A group of Fighter/??/White Mage/Black Mage makes the game relatively easy (replace "??" with a Thief, Black Belt, Red Mage or another Fighter). You'll also have to do loads of leveling up at the beginning of the game, unless you decide to use (SPOILER)the finger point NE of Pravoka for leveling up.
