I have to go with Final Fantasy 7 as my favorite game of all-time. I think it had some of the best music in the series, but it was the first game that I thought had such a storyline that got me into it. I genuinely wanted to see what happened to all the characters in the game and find out more about their storied pasts. Not to mention, I just found Sephiroth to be QUITE the badass too...and I loves me a badass bad guy in a book/movie/game. I loved the battle system, I loved being able to customize characters with the materia system...to this day I still love replaying it every now and then (which finding the time for is becoming less and less frequent).
