i saw that the first time i played, and kind of laughed
but i dont think theyre trying to copy dragonball, at least i hope it isnt...though the similarities are very apparent. was square called square enix when they made ffIX? because toriyama works with enix...(dragon quest)... dragonball is very popular in japan(well, it is in every part of the world, but...^^
still, its very interesting.
edit: oh, dont forget, theyre both from a different planet
