If may stick my nose into this conversation, I would say that this is what makes each of us unique. Mark, you are absolutely fantastic at creating the resources, that the rest of us use to do what we do. Not just for your own games, but for all of us.

My own maps wouldn't be half as good as they are, if it weren't for the resources (and the guidance!) you've provided the last five months.

And Mouse, your maps may be for a book, and that's perfectly fine, but your maps could become gaming maps easily. Especially the city map you're working on, and the observatory you've recently finished. Your maps have a multi purpose quality and a beauty that makes others want to do D a reason to use them.

And mine? Well, hopefully my maps open up story ideas for the people that see them. Mark, you once said that what you like about my maps is that you can see a story in them. You may not know what the story is, but you know it's there. There are two reasons for that. One, obviously because my maps are for a specific campaign, so I'm embedding clues into my maps, to help my players, and to help move the story along.

But a GM could come along and see one of my maps, wonder about the story my clues provide, and start coming g up with his/her own answers as to what the story is. Next thing you know...he's come up with an idea for his own players.

I would say it's the need that is the root and trunk of the tree, and we are all its many branches, and fruit, fulfilling whatever niche our maps fit Into.
