no. seriously, no. in the kingdom hearts realm: squall (leon), yuffie, Aerith, cloud, and cid lived in hollow bastion, unlike the real thing where they are scattered throughout different final fantasy worlds. if you want the ffX world (Spira), too bad cuz Tidus and Wakka lived on Destiny Islands. Auron's dead so he's with hades in the underworld. what? you want to have a world with less cool characters? So, what's the point of including ff worlds if the characters that inhabit the world dont even live there? Besides, ff worlds are big. Unlike kh worlds which are one town equivalent to one world, one ff world has so many towns/cities/villages/etc.
