Thank you, Lord. Truth tell, I've been creating RPG maps for over 20 years for my own games, and in the beginning they were strictly hand-drawn, not digital in anyway. I'd create mostly as drawing only, no color, rarely I'd add colored pencil to the work.
As an artist, I am lazy. I work hard to create the image of the final map in my mind to viewable format as fast as possible. The key here is "as fast as possible." I don't want to spend the time, perhaps that the art deserves. So, I don't care about the method, I care only for the result. So I work very fast, to get the result I require. I really don't want to spend the time to do it entirely by hand. Digital brings my work to light speed.
I may yet find the project that deserves doing it the old fashioned way, in the future.
Lord, you may have planted a seed...
