A superb series in my eyes. I have played most of the Final Fantasy games:
FF I- Completed the Nes/PSX/GBA versions and have done many different challenges. Liked it much and by looking its age, it is really good. Only drawback is that you most-likely don't know at some points what to do.
FF II- Played it only for a hour on my mobile phone( the Nes version with a emulator for mobile) and PSX version for half a hour. Tho I think the leveling system is cool, somewhy I haven't found time for it.
FF III - Half game complete and still playing a bit.
FF IV - Completed only once, but really liked everything in that game (except the water dungeon after the first time in desert)
FF V - Got stuck at somewhere when was little and haven't played more
FF VI - Completed and think it's one of the best FF-s
FF VII - Completed several times and love it much... can't get enough of it.
FF VIII - Lost my saves at first quarter in the game and never started again...
FF IX Completed it about 15 times... never got enough of it and done very possible challenge I know
FF X Like it really much... just super game, but because I don't have a ps2, cant play it much. Only sometimes at my friends house.
FF XI - The absolute best MMORPG I have ever played. Just the depth and party and world and story are so good, that I played it about 3 trials in a row ( Will start to pay if I find a credit card )
FFT - Played a lot, but never completed.
FF TA- Completed it about 4 times. Like it much

SO as you see I am a big FF fan... can't wait til FF XIII/FF XIII VS/ FF XIII Agito and of course FF VII REMAKE for PS3
