My Fav is FFVI. The story, the music, the characters, the graphics (at the time it came out in the USA anyway), the fact that the main characters were girls Terra for the first half and Celes for the second (a big deal for a teenaged girl sick of every single game/movie/book/story/etc being about the guy saving the weak and helpless damsel in distress with the power of testosterone) all come together to make my favorite video game of all time. It still holds up today, even if the translations is a little dumbed down to get past the US censors. It was the first video game I ever played that was more about the story and the characters than about playing the game, and I still listen to the soundtrack often.
