The problem is that people are looking for "creativity" from Square in the wrong places. The Final Fantasy series, at its best, would be a blank canvas for them to experiment on, thereby producing their best games, over and over, without having to stick to the same formula.
They succeeded with this model using Final Fantasy XII, making the best Final Fantasy in over a decade, but I get the feeling that Western fanboy reaction to the changes will....
Have no effect whatsoever, actually.
Here's hoping that XIII is just as different from its predecessors!
