Yeah, I know that everyone who has something to say on the matter has probably said it.
Still, with my raging love of the Rules Cyclopedia, (it's my "theoretical desert island" gaming book) I would feel odd not making a comment.
I like what the author has done by extending all the demihumans out to 36th level. I know there are rules for such in the Cyclopedia, but I like to see them fully integrated from the get go. Ditto for demihumans and Weapon Mastery. I'm not sure if the Weapons Feats of Dark Dungeon and Weapon Mastery from the RC are 100% identical, but I'll probably have a look one of these days. The skill system has been cleaned up a little bit, as well.
On the downside: I know you can download this for free, and I know it is a non-profit labor of love by the author, but that "found artwork" look is just awful. I would actually rather have a gaming book with no artwork than with that generic looking crap. Also, not quite as economical as OSRIC, but hey, I shouldn't be too tough on it... nowadays, $13 for a softcover and $26 for a hardcover is a steal.
There are a few idiosyncrasies that the author has introduced, for instance, the path to Immortal ascension is a little different, and he has added firearms (and the special "red powder" that makes them fire) as an implicit part of the setting.
I will probably not be buying this, as I still have a perfectly serviceable copy of the RC, but I am glad that "Mr. Blackball" took the time to put this together.I consider the Cyclopedia to be one of the top ten greatest gaming books ever released. However, it isn't always possible to find a good copy at a reasonable price; as I am typing this, the Cyclopedia's start at $59 on abebooks.com, which is where I bought my current copy around seven years ago for around twenty bucks. The release of Dark Dungeons makes it readily accessible to gamers who might never have had the pleasure of perusing the RC, or who need a "working copy" to save wear and tear to the original book. You know...maybe I'll get a physical copy of this after all; I'd like to have a backup around in case my copy of the RC starts to look a little threadbare.
The last thing I'll say about Dark Dungeons is this: bonus points for blowing the raspberry at Herr Chick.
