Ohh Final Fantasy threads are always great.
I must start off by saying that if you have not played any final fantasy earlier than 7 then you are very much missing out on some fantastic games.
My favorite FF is definitely 6. The story and character development are probably some of the best I have ever seen in a final fantasy series. FF9 is also one of my favorites, do not know exactly why, I just had a large amount of fun playing it. Also the card game in 9 was amazing.
Also for those of you two arguing about FF8, I'm going to have to agree that that game was one of the worst games I have ever played. Nothing was good about it at the time except for the massive leap in graphics.
On a side note, I am currently playing through FF13 and I must say that it is quite amazing. Everything from the gameplay, graphics, art, music, sound, characters, and I would say story if I actually knew what was going. So in all I would say that everyone who likes FF should pick up this game, as it will probably be one of the better ones that I have played.
