As for the topic...

The series has always been about innovation so it's logical that it will continue to evolve one way or another. Lately, I'm getting the feeling that Squenix is starting to work on the concepts of reinventing "fantasy". Many of the projects helmed by Nomura/Nojima/Kitase always take a much more "interesting" approach to their ideas of fantasy and world design.

Sakeguchi/Amano/Uematsu teams tried to create the most epic of fantasy stories and kept trying to reinvent the games. N/N/K as I've stated took this concept and decided to try and escape the normal trappings of "high fantasy" while Matsuno's team tried to bring a sense of realism by placing greater emphasis on history and politics in their game desings. All three styles are successful and all three teams have done their fair share of triumph and failure. I think this is one of the reason why the series has always kept my interest.
