While the October Challenge was a good idea (and I certainly enjoyed it) I think it may have been a little overwhelming. It asked for 6 NPCs, a town (however small) and all that comes with it (reactions of NPCs, entrance, etc.), and 3 plot hooks (or 1 plot hook and 2 "points of intrigue"). While the September Challenge came with similar requirements, they seemed to flow more naturally from the Henchperson and also did not seem as important.
For instance, the September Challenge asked for the following:
A brief background for the NPC
Description of his/her relationship with the BBEG
Details on his/her modus operandi
Suggestions of creative ways the NPC might be used to develop a story through direct or indirect interactions with the PCs
Both the modus operandi and the background are a part of the NPC creation process itself (though not a step that is always included). While the relationship with BBEG and the story development interactions are related (though perhaps not directly).
The details for the town could be related (since at least one of the 'prominent NPCs' is likely to be involved in at least one of the plot hooks), but not necessarily. I am not complaining about the amount of work involved in the challenge (though it might seem that way). I am merely hoping to find a way to encourage other posters on Myth-Weavers to contribute to the challenge for next month (whatever it may be).
