You've gotten many different suggestions here and I'd be lying if I said I couldn't recommend all of them!
I thought FF IV, VI, VII, VIII, IX, X and XII all to be spectacular games. If you're not one for turn-based gameplay, XII is the game for you. If you don't mind that and want more of a modern gaming experience (voice, graphics, etc) X may be the game for you. If you don't mind playing in 2D (or maybe not with FF IV DS) I'd recommend both IV and VI above all others. VII, VIII and IX are also all great in their own regard and I'm sure if you're an RPG fan you'll at least be satisfied with them.
