The only reason I would stay away from a period piece is because sometimes the women are painted in a very stereotypical weakling, wallflower way - that's something I don't want to do. I want to show strength in the women I play, and a journey of some sort.
Sometimes it's not like I write very specific, it's more like I add an atmosphere almost to something that might have been quite awkward in my mind from the beginning. Something has happened and I want to force myself to think of it in a more positive way. And then I force myself to write something that convinces me that this is actually something pretty good or something that I learned something valuable from.
