FFVII is widely claimed to be one of the best, and to some, the best FF ever created. IMO it's definately the best since coming to the PlayStation. I've beaten FFXIII, I'd give it a 6 or 7 out of 10. I played about 5 minutes of FFIX and put it down. I can't remember why. Final Fantasy Tactics is a damn good game as well. The gameplay is completely different from the rest of the FF series in that its a turn based strategy game, much like Ogre Battle, Tactics Ogre, or Shining Force. I own FFX, and beat it as well. Pretty good game, 7/10.
