Three Days to Kill is a weird one, since the OGL didn't have "Product
Identity" when we did it. As I see it, there are indeed three things in an
OGL'd product:
Open Game Content - open for all the world to use, reuse, and reproduce
under the terms of the License
Proprietary/"Closed" Content - material that does not involve any Open Game
Content (for example, the color text of a monster description which is not
derivative of previous Open Game Content, does not include any rules
information, etc.; designer's notes would surely fall in this category)
Product Identity - things that must necessarily cross between the two; e.g.,
the name of a character who is proprietary but needs to be described in Open
Game Content sections in terms of the rules
Had Product Identity been a term when we did 3D2K, we probably would have
"identified" things like proper names as Product Identity. Or we might not
have bothered, depending.
