Ravenloft: Silver Anniversary Edition has really good material, but you should know that already since this is the 3rd incarnation of the original Ravenloft adventure. The second, House of Strahd, got a good review in Dragon Magazine (#205), which said it was even better than the original. I suspect this is more faithful to the original, so I'll eventually have to get House of Strahd as well.
Anyway, about the quality of the pdf itself: the bookmarks are good and the scan quality is decent/good, but not great. However, it is quite easy to read and there's no significant problem. Unless you're specifically playing 1st edition or want the original just because you're interested in it, I would think this is the one to get instead of that.<br><br>
<b>LIKED</b>: Great material, good scan and bookmarks.<br><br><b>DISLIKED</b>: Scan could be better, and it would be nice to know how this is different from the original (or House of Strahd) without having to actually get the other ones.<br><br><b>QUALITY</b>: Very Good<br><br><b>VALUE</b>: Very Satisfied<br>
