I hope no one thinks it's too self-serving for me to suggest "Maure Castle," a 97-page adventure that took up the entirety of Dungeon #112, our 30th Anniversary celebration issue.
"Maure Castle" is a "return to" WG5, "Mordenkainen's Fantastic Adventure," which was written by Robert J. Kuntz and Gary Gygax way back in 1984 (but appears to have been around since a 1974 Kuntz-DMed playtest, making it 30 years old this year, just like the game itself).
We got Gygax and Kuntz to help us update the adventure, with expanded material by the Dungeon staff. The whole thing was a labor of love, and (in my opinion) was very respectful to the original adventure.
Fans of the "first edition style" of adventures, or of those adventures themselves, will probably enjoy it.
We STRONGLY considered doing a "Return to" the Barrier Peaks, or even just a 3.5 update with expanded material, but ultimately decided that such a project would take up about two regular-sized Dungeon issues, which was simply a gamble we couldn't take.
