Well, I hate to sound like some kinda 1337 FF-lover, but the crystal in the magnetic cave was actually the earth crystal....the fire crystal was captured during the raid on Damcyan.
Heh, I can understand totally wanting to take the games slow and enjoy them, but I have a pet peeve where I get annoyed if I have strated too many games and not finished them.
Thus do I end up usually finishing most games a start, often to a deep welling sadness that there is no more to play.....
Then, back in the days when there weren't 3-5 good RPGs a year, I would often play through the whole game again, this time taking it eeextra slow, searching out all the little nooks and crannies and building up invincible characters.
For some reason, I found it was more fun to rush through the game for the simple fact that I missed a lot of items and didnt earn hardly any levels, so the game was more challenging.
Oh goodness, Im rambling, Ill stop :-D
