I can customize things to a certain extent, but I'm more about the artwork and don't want to be a content creator.  Not all of us are talented enough to make 3D models.  I can, and have, made some props with primativies if I'm in a bind.  I'm sure I'm not alone in this, to me the arduous process of human figure creation is the difference between buying a car from a dealership or building one in my garage.  Human figure creation can take months (or years), I'm not going there.
