5 Stars! This is a great product both as a .pdf and as a module.
As A PDF: As a .pdf it scores big with me for high resolution graphics, cover, images, etc... Text is completely selectable, and pages have no scanning anomalies. I get the sense this is a port of their original files and not a scan of the paper product. Printing might be a small issue for some due to all color, no black and white version. Also it has 'edging' on one side of each page that would waste quite a bit of red ink. Again, not a problem for me as I will unlikely ever print.
As A Module: (Play tested with gaming group, I am DM, we are about half-way through): Wow, one of the best to come out of TSR in a long time. Well crafted adventure that themes on the idea of a large goblin invasion of a small vale. The vale itself is well described and is easily inserted into most campaigns as it is relatively self-contained. It is a solid 'DnD' feeling module.
It had a good logical flow and my players naturally chose the directions the module intended. It is very easy to add your own quirks and twists within the campaign. It not only has smart encounters, but most encounters have a nice twist of either terrain, unique monster traits, etc., that kept encounters interesting. Played straight out of the module, my players generally have had no problem surviving to date and truly seem to be enjoying themselves.
If you are in doubt, press order. I assure you that you will not be disappointed. Check other reviews on Amazon.com or Enworld.org if you are still waffling.
This is a great .pdf of an excellent adventure. I highly recommend this product.
