Oh man! You're missing out!
Back in my video gaming glory days (i.e. 1998-2005), I played all the Final Fantasies except 1 and 2. Love that stuff. 9 and 10 are my favorites, and 5, Tactics, and Tactics Advance, are my least favorites.
FFIV was only out for NES (or SNES?) as the "Easy" version in the US -- and they released the "Hard" version way later, packaged up with Chrono Trigger in a PS1 box set. I loved Chrono Trigger and wore that game out, but FFIV was too hard for me. I could have gotten farther into it, but it would have required a lot of training, just wandering around and fighting random battles for hours in an attempt to level up, buying items as needed. (I'm sure there's an RPG term for that, but I don't know what it is.) I don't find that fun, so I gave up halfway in.
