If you just want the short version, this is one of the good pieces, and is worth getting if you can at all afford it for more details, read on.

Hence, I intend to review particularly good, or bad, pieces in the hope of pointing people toward or away from them. In other cases, really good and useful material is now dirt cheap, and many people simply don't know about it or aren't willing to take risks. More importantly, the high price some of this material carries means that not everyone can just buy it all and use what they like if you're looking for campaign material, rather than 'collector's items', knowing what to skip can save you a bunch of money. The differences between first and second edition AD&D are not great, which makes old 1st Ed material useful to a GM who doesn't mind making a few minor alterations. After all, this is an out of print 1st Edition AD&D module that typically goes for $30 or more used, when it can be found at all. Some of you are probably wondering what the joke here is.
