The module I was writing has stumbled a bit while I got inspired in a totally random direction by my brother. I think it might take all of my focus to finish what I've already started, even if I don't like it as much as the other one I could design.
The thing that's really cool about trying to do a 1-month module is that it really limits the sorts of things you can do. You can't get all grandiose and spend weeks planning and plotting, and days drawing out the perfect map, and then let it percolate. It's 30 days, start to finish, from vague idea to poorly written descriptions of places to (with any luck) a halfway decent module that's about something that isn't stupid.
This first module is going to be absolute rubbish. It feels like the more I think about it, the more I realize that it's not the direction I want to be going. But that's part of the challenge too, I think- I'm halfway through the month. That's not enough time to start over, even with what little I've already done. Plus, I don't want to waste my really cool idea on a half-month project when I could just finish this kidnapping module thing and then give the full month of love to the other idea.
So I've got to really figure out what I want from this module, and that's a good feeling. Get it right, turn an ok idea into an awesome one, and then we're golden.
