Heh,
Do not expect a treatis in response.
When I initially began creating adventure material I assumed that the GMs utilizing the work would prefer substance without window dressing, the latter being properly the realm of the GM so as to suit the campaign world and player group.
I discovered I was by and large erroneous in my assumption, so in later modules I added considerably more material for the GM to read aloud to his player group.
Currently I am rather loathe to design new adventure material of this sort, as I have done a sufficient number of modules that doing another risks repetition. I feel rather constrained thus. Coming up with something different and in at least some way surpassing my previous efforts (in my own critical view) is not a task undertaken lightly...if at all.
Cheers,
Gary
