FFIV-VII was the series high, if I had to pin point one game it'll be FFVII.

Final Fantasy set the standards in terms of how RPG's need to be made. The series reinvents the RPG formula again and again and leaves every other RPG series in its shadow. When we wait for the next Final Fantasy, were not just waiting for the series return, were waiting to find out where the whole RPG genre is heading. Its all these reasons as to why Final Fantasy is the king of the RPG genre.
