VIII is the best. Having completed IV, VII, VIII and X, got to the last boss on IX and died choking on my own vomit and simultaneously falling asleep, and being about 3/4 through VI, I have a god degree of experience with the series. It was the first RPG I played, and enjoyd it massively. As for ???????'s comments, I barely ever used the GF throughout the game. It's all a question of how you play I suppose. I never get sick of it, love the storyline, love the characters and love the junctioning system. The story is really quite emotionally involving, and a sword will never compare with a gun-blade for pure satisfaction value. Slapping down R1 with each attack with Squall is about as much fun as you can have in less than half a second, and to my knowledge the only time in the series you get more involved in attacking than selecting the 'attack' command.

Also, Zell is God. In the beginning, there was nothing. So Zell created stuff. Then he punched it. The end :P
