While the black and white pages of this module are very crisp, the color maps, particularly the large map sheets, suffer from some very obvious quality loss. These oversize pages are fine for viewing as an entire page at once, on a monitor, but if you are zooming in, or for printout, especially at full size, the quality loss is substantial.
The module itself is an awesome 2e AD&D adventure... and ports quite easily to first edition AD&D as well. Migrating it to 3rd or later editions is substantial work, and would require significant changes to maintain game balance.
If it hadn't been for the color map quality loss, especially on the large poster maps, I'd give this 5 stars, quite handily.
