You'll have fun on this one
Play LOTS of cards and learn card mod (*cough* 20 Elnoyles, 1 Minotaur, mug a small lizard in the training center for a few Dragon Fangs) IF you can do this on the first disk you more than likely won't have very many problems!
Your Gaurdian Forces (GF) can make you WAY more powerful than you expect. So look into using the Draw command a few times (even on Bosses) with the one of a kind Junction System! It literally works to YOUR advantage.
And just like every other FF, take the time to do sidequests. You never know what might happen...
