As others have said this game isn't too difficult compared to some of the earlier ones, although some of the forced mini-games annoyed me. And some of the bosses might be a little tough if under-leveled (Black Walz & Sealion are tricky as you only have Zidane when fighting them early in the game), also DON'T use Fire against the Iifa Tree and listen to the little Moogle in Gizamaluke's Grotto when he advices you NOT to climb up the vines.
