Thieves of Fortress Badabaskor
Citadel of Fire
I did the maps and layout for all three and I am co-author (with Bob Bledsaw since it is a remake) of Fortress Badabaskor. So if you want to see how I write up dungeons in addition to mini-setting this is your chance. Badabaskor is probably the closest thing you will get to a sandbox dungeon. Like the original it isn't a place that you hit and clean out. But a location that you can revisit over and over again.
There is now a 10th circle of hell reserved for 3.X stat blocks. I don't have any serious issues with 3.5 as a game or using stat blocks. Writin them however is a whole different story. I have to do a lot technical writing as a software developer often to exacting standards. Writing 3.X stat blocks is the most miseriable piece of technical writing I have ever had to do.
Citade of Fire is similar to Badabaskor but centered around a wizard's tower and the nearby communties. It is probably has the most stuff packed in and includes the citadel, a village, and a necropolis among other thigns.
Dark Tower is a straightforward conversion of the original. However as classic the original was there were some issues in the layout and format and I think even if you don't like 3.X you will find this version a lot easier to use.
So again after Decemeber 31st you won't be able to get this anymore new.
Note: Please don't let the presence of 3.x stat block turn you off of these three modules. We were able to up the page count on all of them so nothing was cut due to the presence of the stat blocks.
