Final Fantasy 4 isnt too hard, it just requires time to be put into it. If you dont take time to level up with random fights every now and then, it'll be very hard. Also, go buy some phoenix downs, fighting random battles will also get you money. If you're on the playstation version of the game, you'll have to do more leveling up because that version is the hardest. But yea like I said...it requires time to level up or it'll be hard.
