I think the face room is the most underrated feature, and I find it very useful. For example, the image here is the standard P5 Judy figure after just a few seconds of playing around in the face room. It may not be the best face I've ever seen (LOL), but it certainly doesn't look like Judy anymore. ;-) I'm glad people like Geep are here to help others understand and appreciate what the face room can be used for.
