I know you changed your (and rob's) greyhawk campaign around for publication. How much of the setting was developed during actual play. (as opposed to detailed for the published setting. )
Further Greetings, Mistere29,
You are ahead of Rob and I in regards the re-creation of our original dungeon levels. I am nearly finished with new campaign-base material for the central thems, the ruined castle and its many dungeons. Rob, meantime, is devising an introduction to Zagyg, the Mad Archmage. All of that will take a few more months to complete. When that is accomplished, we will then turn out attention to the castle and dungeons.
We will use my original scheme of the dungeons, altering them as need be for coherant presentation to a general audience of GMs. That means a lot more text and explanation, for I winged encounters, and as Rob learned from me, so did he. The major features from the original levels he and I designed will be included in the re-design of the castle, just as my original work was incorporated into the huge new dungeon complex Rob and I created by combining our respective castles. Additionally, as that complex was explored and exploited, we created new levels and changed things. In all, the original work was one that was in progress, continually in flux of change.
We will do our best to make the printed version not only true to the spirit of the underlying material, but also accommodating for GMs who wish to have "living" dungeons.
Finally, we will not give all away. Where there are great mysteries involved, such as the Great Stone Face and the Disappearing Jeweled Man, we plan to offer the GMs several possible answers
Overall, the PCs adventuring in the dungeons will encounter the same challenges as faced the original delvers in 1972 and onwards, that Robilar discovered and Mordenkainen met.
