The Special Limited Edition Boxed Set was distributed in September 2012 in PDF format to customers who had pre-ordered the game in early 2011. The PDFs were released in advance of the shipping of the printed boxed set.
The page counts include illustrated cover pages. The "no art" edition PDFs include cover illustrations, but no interior artwork.
Publisher's website blurb:
Delving Deeper RPG closely emulates the rules of the earliest version of the world’s most popular roleplaying game. Go back to a time when every weapon did d6 damage, clerics could cast no spell at first level, only fighters could use magic swords, and if you wanted a locked door opened you had to bash the thing in! It is difficult to imagine in a world where multiple, weighty tomes comprise the rules; but this single, small book contains all you need to build a campaign that can span decades of real time! If you’re tired of trying to find the rule for determining whether your fighter is left-handed and is able to swim and just want to kill some goblins, have we got a game for you!
Delving Deeper is an attempt to recreate the gameplay of the early editions of Dungeons & Dragons. The rules are divided into three booklets:
Volume 1: The Adventurer's Guide (42 pp.)
Volume II: The Referee's Guide (34 pp.)
Volume III: The Monster & Treasure Reference (42 pp.)
when we can determine this is the same as Delving Deeper Boxed Set, we will merge the two Items
