I only just finished it the other day. Oh and I pretty much just employed the strategy of casting Aero and then just hacking the crap out of whatever I was fighting at the end of the game. As long as you know where the X button is and you dodge the major attacks and cure regularly and you'll be fine.

I thought it was way too easy, but I guess there's still Sephiroth to beat - the main reason I played the game in the first place.
