There are so many individual issues, but it all boils down to the same thing: over-design. Every character, every outfit, every game mechanic, every plot point goes two or three steps too far. There is elegance in simplicity, finesse in restraint, and confidence in understatement. Since the breakout hit of VII (except for IX), every successive entry has tried to restate but still surpass the same few ideas by adding more layers of complexity. Whether it's adding more belts and toggles to a character design, more phases to a boss fight, or more lines of dialogue to a dramatic exchange, the credo has been 'more is more, and more is better'.
