CD Identification Number:: T-22202G
The copy of the game I recieved came in a nice cardboard cover that contained the disc and manual in a common jewel case, and then an extra booklet which I've picked up is supposed to be a "Secrets" book. I'll assume that probably means a little mini-hint book. (There is an actual official Players' Guide type book for it, however that will likely not show up on the site itself.)
Note that the included booklet's back cover, front cover, and first page (in that order) form one long somewhat strange image. But actually the included booklet is full of strange El-Hazard character imagery.
