FF4
It's the first game I remember playing and telling myself in my head, "this game is freaking awesome." It just had a great story. The betrayal by kain, Cecil's dark past redeemed, the spoony bard angering Tellum, etc. It was just a great game with an interesting story. So many characters with their own motives and purpose. I could go on forever about 4, but i'll leave it at that.
