I take it you haven't seen their OGL statement in their books? They let down the side there.MCDM continues to be the only RPG company I can think of that is this transparent and honest when it comes to their design decisions, something that it'd be great if it became more widespread in the industry.
TLDR; we get to use previously created Open Game Content, but our mechanics? Naw, that's all product identity.
They're not alone in this. Goodman, Monte Cook do it too. Becoming less relevant as they cease to use the OGL, but still most definitely, not cool or honest.
