I hated the graphics in X I much prefer VI and VII graphics
but I think that the worst to happen to the FF series
(other than the death of the world map and therefore
flying around mindlesly in an airdhip)
was the introduction of the voice actor
I took out all the imagination and personality
out of the characters. plus the characters are
getting stupider looker eg. Tidus, Wakka, Eiko, etc.
