To be honest I never visited the page, I was just curious because of how Male_M3dia put it.  I've often wondered because If I recall, I think even DAZ do it as well, I don't see why Victoria 5 is a Base or should be called one, because like you said, it's a shape, a character.

To me a base is the figure itself, the geometry a character is based on.
