as far as i know , square enix owns the final fantasy franchise. they just thought that it would be best to put it on the gamecube in this case.
in the future, they have planned for things on the ps3, nintendo revolution, and the xbox 360, so i guess all of the next generetion consoles are getting a good deal of the ffs. (i do know that most of mistwalker's games will be on the xbox 360.)
and how did they ruin the classics? (i assume you're talking about the ones remade for gba) granted, they made them easier, but that in no way is nintendo's fault. (SE made the game, they just had it published as a nintendo gameboy advance game.)
i just dont understand why people have to bash nintendo all the time...
