But... that doesn't make sense. FF 1-6 have more in common with DQ 1-7 than DQ 8 has to do with FF in general.
The only thing that DQ 8 has in common with FF is that like FF it moved into full sized 3D models. But that doesn't make it any MORE like FF than DQ 6, because you could say "Like FF 6, DQ 6 was a standard sprited overhead perspective RPG released for the Super Famicom."
