I am also preparing for publication (most likely in PDF form because of its immensity) the release of "Lost City of the Ancients" (aka Lost City of the Elders). From my auction scans I pieced together the map which was unfinished at the time of auction. However, not all parts align perfectly (probably my inexperience with Photoshop).
There are over 100 jpeg and pdf files related to this as well as many other MS pieces I have added since then. The product is way beyond PPP's means to publish in print format due to its size and content, which has a heavy weight on maps (with the combined 40 x30 color hex map there are at least 15-20 other maps from interior buildings, sewers, etc) and illustrations, and probably over 60,000 words of text.
Due to this I have apportioned my time thusly: Castle El Raja Key levels, Old Castle Levels, Memoirs and have added this project as a PDF only, which will allow it to be released, otherwise, it's a no-go. I have had hundreds of inquiries over the years about this project. Its scope has always been too large for a print endeavor and would eat away at my time to a severe degree just ordering its parts for print, but in PDF it becomes viable in the not do distant future (mid to end 2010).
Though I generally dislike polls, I would like to poll at least the readership here to get an idea of the reception of such a PDF product which would otherwise leave a part of RPG history resting in the hands of those who bought the originals at auction several years ago. I have no idea what I would charge for such a thing, as well, but the content will be huge, including a short story of EGG's first adventure into it. Here's an extracted part from the Intro:
"...Historically this is the first off-world (or planar) adventure from the Original Campaign. The city as is historically recorded existed out of the current time stream and out of known space. It was a place of unknown and unfathomable events. So too was it an experiment and thus of great interest to those vested in discovering the arcana that derived from it. Its legend is only whispered among the seekers of arcane knowledge and its mere mention summons images of dread demons and less savory kin called from the depths of cold space. Its total history will never be known lest the god who created it foretells such a time when this might pass. Its ancient magics and beings have defeated the greatest of wizards, driving many to an early death or into the oblivion of irretrievable insanity.
