Yes. That doesn't necessarily mean they don't produce a steady stream of income.After the initial boom that comes with an new edition, they become less hot items and sell less.
Ryan Dancey said, back around the launch of 3E, that the biggest revenue stream is from sales of core books, especially PHBs. Is there any reason to think that has changed?
But what reason is there to think that they are generating no revenue? A new D&D boardgame was just released. Presumably that will generate revenue. They have just released a free PDF which is, from a marketing point of view, a teaser for a new book. Presumably that book will generate revenue.Not making stuff is not very profitable either. You pay employees to generate no revenues.
I would guess that Paizo sets a lower expectation for return on investment than Hasbro.Yup, and it seems Paizo is very rational.
I would also guess that Paizo doesn't have as many alternative options for places to invest its capital as does WotC/Hasbro.
It is possible that D&D is, in fact, incapable of generating sufficient return on investment to satisfy Hasbro, in which case we should expect the size of the WotC D&D division to reduce over time. But even if it reduces to zero, that wouldn't show that WotC were economically irrational in not producing more supplements. It would just show what many have long suspected, that there is not much money in the RPG business! And it would confirm the scepticism of those who think there is little money in licensing the D&D brand.
