Modules in blue have elements that presage later storydrive focus, but still retain elements of old school design.
Modules in yellow depart significantly from the norm in style or settling, either because they were rushed to press (WG4), or made different assumptions than old school design.
While it is somewhat arbitrary, adventures after this period are increasingly story driven, mystery oriented and not what I would call "traditional" AD&D adventures. This does not mean they weren't good or well written. There are some award winning modules after this period such as Ravenloft, Assassin's Knot and others. However, with the advent of Tracy Hickman and others D&D began to be seen differently. The effort seems at delivering a preformed storyline, instead of background story elements that could be used to focus or expand upon. There was a mystery element with a central purpose of solving the mystery. Others, such as the UK series focus on not using violence to solve problems, and we begin to get large campaign style mega-modules that are de facto designed to carry PCs through an overarching storyline.
While series such as A, G, D/Q did have a storyline connection and internal dynamics that could be utilized by PCs and DM alike, it was not the focus of the dungeon. One could get through the series and not have a strong sense of the unfolding story or dynamics. Many of the adventures were designed with the idea that the DMN would expand upon, flesh out, or focus on certain elements, effectively making the adventure their own.
No, not all adventures after this period eschew dungecrawl, wildernesscrawl or old school sensibilities. It is a spectrum of course. But my point here is to illustrate that there was a distinct break in style of module creation pre Gary (which I mark at 1982/3) and post Gary. Again, this is not to say subsequent playstyles were bad. Long term story driven campaigns were represented all over old school gaming, but the principle design ethos was that DMs did that work, not game designers. This of course would change too.
And I should acknowledge that pre AD&D, adventure and world design was the particular province of the DMs as well, not designers. It said as much at the end of the 3rd little brown book. But with the huge success of the Original D&D Greyhawk and Blackmoor supplements it was clear that people wanted it. So the designers at TSR, led by Gary, set out the types of dungeons they were running. Those are the modules represented here.
A more thorough analysis remains to be done, but I am satisfied with this preliminary list, which I believe represents an old school design ethos that changed as the game and some of its gamers changed.
