Hm.

I really wish they hadn't included something in the game that was nearly impossible to find without Internet guides-- makes me feel cheated, somehow.

Similarly, I only discovered how to get Yuffie and Vincent in my group party with FF7 (or that I COULD get them in my group party) through stumbling onto a website about it. But I can see how someone could actually acquire Yuffie and Vincent through serendipitous gameplay.
