Well, it has for me anyway. I just got the Japanese playable demo along with the Japanese version of Final Fantasy VII: Advent Children Complete in the mail today and I am going to play it to death. Later, after giving it a real good solid play through, I'll write out a full report on how the game looks, plays, and any other details that may come up that are worth mentioning. I'll let you all know how it goes.
