because IX was a tribute and the Swan Song to all FFs prior to it, it was actualy originaly marketed as a tribute, it was their way of saying goodbye to old outdated conventions while giving what they thaught was the best sendoff they could... of course years later they negated that sentiment by making enhanced ports and remakes of I-VI... ironicly i'm still waiting for those V&VI remakes, i hope they don't mess up the VI remake like they did with the enhanced port by removing the torture scene...
