So what would one expect to pay for an adventure?
I would reasonably pay from $15 - $40 for adventures, depending upon how large and expansive they are, and if they also have area info, like many of the old Shadow World modules. In a quick list format;
$15-$20 = Fairly short and sweet adventure that can be played in about 2-sessions, but is possible to get done in a singel session. Not very much info about local area, just enought for the adventure.
$25-$30 = Here we are getting into a more complicated adventure, one with several "steps" that are needed to be accomplished before finishing. It could be finished in 2-sessions, but likely will take 3, possibly even 4. More detailed information about the area, including things that might not be used in the adventure.
$35-$40 = Here is more like an area sourcebook with an adventure along side, or a long adventure with many, many "steps", as well quite a bit of information about the local area, including prominent locals, places, laws, etc... even stuff not needed for the adventure, but will add with flavor.
In ALL cases see the last question and answer.
How many pages is the normal adventure module?
I don't think there is a set number there. But, I would prefer my modules to be minimum of 20 pages, usually around 30-40 pages, including maps and specific individuals and creature descriptions.
How long does a normal adventure run?
Again, no baseline to use here. But, I like my adventures to be from 2-3 sessions in length, with sessions averaging around 6-hours in length. For some more involved adventures, i am good with a 4-5 session running length.
What would be your expectations for a normal module, such as maps, NPC's, art?
I have made my preferences in this arena very clear in the past, but here it goes again: ART!ART!ART! & MAPS!MAPS!MAPS! Oh, a few to several moderately developed NPCs are nice, as well, but I don't have a problem taking minimaly detailed NPCs/creature-beings and going into detail on my own. For example: The adventure Cult of the Third Moon in the
Jamain, Land of Twilight setting book, has a high-priestess, some lesser priestesess, and a Caliban-like dude, all of which have some, but not much detail to them. I have deteiled each of them out, individually and how they work together (or not-so-much) to the tune of several pages (~6) worth of information. And, done several - approx. a dozen - of the nearby townsfolk nearly as detailed, for another ~8 pages of info. So, while having it is nice, I don't have much problem doing that on my own, what I cannot do is draw worth a damn, so art is critical. Now, I am pretty-good at maps, it is just that they can take a long time and having some pre-existing maps is a huge time saver.
