You should play Fallout 1 before launching such assumption. I haven't played all FF but the III ie the VI in Japan if I remember well, the IV and the VII plus a bit of I&II.
A better story polishing just can't match a more adult story, plus alternate choices plus no random encounters that pop from thin air, plus no harassment of repetitive fights, plus no forced grinding.
