D&D IS undermonetised, though.
I agree that I worry that corpo-speak and myself are talking about two different things - but it has always been shocking to me that we only recently have been able to buy, say, mugs with the ampersand on it. Or how World of War craft and all the money it made (not to mention all the other CRPGs) could have been the success of a D&D game, had the brand been more sensibly managed.
So many things that have been wildly successful owe their existence to D&D. Not that D&D hasn't been successful, but I think that it's clear (ymmv) that it could (and perhaps should) have been even more successful, had it not consistently been mismanaged.
Otoh, I don't really see that changing much.
