As far as I'm concerned Final Fantasy IX was the last real Final Fantasy. FFX was pretty and all but by the time a beat I was just pissed, everything since has been down hill. FFXII was a mixed bag for me. There are some things about it that I really loved and there are some things that just suck. But at least it still felt like a Final Fantasy game. FF13 and 13-2 are not horrible, but they got some serious issues, mostly being that they just don't feel like true FF games. They are so far removed in everyway from the roots that it just seems like they are simply trying to milk the name for every dime they can.
Obviously they won't get Sakiguchi back, but they need to let someone else take control before Nomura runs in clean into the ground and beyond. People can talk about all the changes in the original 9 games as justification for the last handful. But there was a consistancy in those original 9. Also they were not afraid to take old ideas and rework them into the next new game. I'm all for innovation and progress, but if you are making cars you don't just suddenly start making speedboats, you make different cars. FFXV is a is a damn speedboat.
