I'm not sure if I read this right, will there be fold out maps with each of these modules? Will they be regional maps? Miniatures scale maps?
If you go miniature scale, I'm thinking you'll hit gold combining short, solid adventures with the Fantastic Locations style maps that are useful during play, at the price point you're at.
And if you're not planning to include them, I'd pay somewhat more per module to have them :-)
