My favs would be FF7, FFTactics, FF8, FF10
FF7 because it was the first game that made me cry then rage at the same time becuase i put all that time and effort into makin aerith a beast and she goes and dies /cry. it had an epic story a vilian that was a true beast and it was the first steppin stone in the ff franchise to usher in the new graphic age
FF Tactics because it was the first FF game i played. It had a great story and had my favorite classes of all time The Dancer and Dragoon.
FF8 because it had a awesome story great graphics a pompous villian that you loved to hate (cough cough siefer) and was the first ff game that not only left me satisfied but questioning did he really survive (Squall's dead theory if your wondering)
FF10 becuase like seven had me cryin like an 8 year schoolgirl, had an epic story, relatable and likeable Character and another pompous vilian you love to hate (cough cough Seymour)
i lookin foward to adding 15 to my favorites jus hoping it live up to it.
