Err yeah, as someone who has played every final fantasy on that list, finished them all, and even the final fantasty games not on the list, i'm going to say, everyone that thinks All the FF's suck...
Go play your sega pico's and eat some animal crackers, because it's time for bedtime you video game n00bs.
Final Fantasy has Awed gamers for years, and will for years to come, it IS the king of RPG's, no other RPG series has pulled in so many fans, i'm surprised it has enemies.
Anyways, this is one huge effing flame war now, so my two cents are that none of the Final Fantasy's on that list deserve the worst title of them, sure some of them were bad, but did you not finish them till the end? There was only one that I never finished.
That one that I never finished, lacked story, a good cast, and complete gameplay. Final Fantasy Legends for the Game Boy.
For those of you that hated 8, yes I'll admit I thought that was the worst one for a while, then I thought about it... And the reason I hated it was the crazy Limt break combos... but I noticed they added to challange, and that is one thing that n00b's typically hate about video games, is challange.
Of course there is a difference between challange and crap.
A challanging game can be beaten, as long as you give it time, and look at it a few ways. (ie. Super Ghouls and Ghosts (SNES))
Crap games cannot be finished due to bugs and crashes. (ie. ET (Atari 2600)) (yes I know SOMEONE actaully finished this game, but they know it's a huge glitch
)
With these two categories defined I think that every final fantasy on that list fits into the challenging category.
