If I am releasing a pack for Maptools is it best to create the .campgn file with the lighting overlays etc or leave that out? If I want it to be useful in other VTTs I'm guessing the answer is, "No". Perhaps adding the fog of war layers should be left up to the GM or I should include maps with and withOUT the FOW layers?

Maybe I'm mistaken on .campgn files as well (now that I'm thinking about it). Maybe .campgn files are for including the game rule system - dang, have to go do some more reading...

Clearly I am only slightly versed in Maptool and not at all in any of the others.
