Interesting ! Maybe a bit expensive if you buy it via an "auction center" but why note ? Me too, I never heard of this Phantasy Star III..or...because I know another french Phantasy Star fan who own a Phantasy Star III "note book" (don't know if the term is exact..) which contain a map of the world(s) : which one ? I didn't know...I'll try to ask him ! I think I'll buy it and I'll tell you about this ! maybe it's the same ??
He also tells me that this "book" was sold in Japan only in may 1990.
EDIT : It's this book ! I've forgotten that he send sme some photos of it before ! I'll try to show it to you ok ?
