Im Defending Nomura.

[Sephiroth]

I am a big fan of Tetsuya Nomura but being a director is a position that brings great power and so great responsibility. You need to be able to plan your projects properly. In all fairness I say it is a mistake that can happen to anyone, especially if so many things change but it should not happen so it is probably the best the way it is. The people I really see possible for the director position of the Final Fantasys are either Hironobu Sakaguchi who is no longer working for them, Yoshinori Kitase, Motomu Toriyama or Hajime Tabata. Directng Kingdom Hearts III and Final Fantasy XV and i don't know what else he did plus partly writing scripts and being the Art Designer is just too much for so many things and you need to know how much you can expect from yourself and what is too much and while it is in the core the same Final Fantasy title all those changes might have caused a great delay as well, while that might not be the only reason.
