Umbran said:I think around here "Core" generally refers to the basic three books - the stuff you know all groups have, that all groups pick up in order to play the game. That, by extension, is the material developers can feel absolutely free to refer to and assume is understood when building a supplement.
If, for example, Warforged are included in the D&DI, if a developer then refers to them in the PHB3, then you have the problem that anyone who isn't a D&DI subscriber can't fully use the PHB3, and that's bad. Over most of the life of 3.xE, WotC was very good about this. I think if they start referring to supplemental as "core" there's going to be a lot of confusion, and perhaps a tendency to allow these cross-references to slip in.
Incomplete cross-book references may sell comic books, but I think in RPG materials they'll cheese folks off something fierce. I really suggest WotC become disciplined about how they use terms like "core".
Incomplete cross-book references were one of the things that bothered me about TSR's later Forgotten Realms products, which had lots of references to other books.
If something is mentioned in a book, it should be explained in that book.
