I don't necessarily disagree. But this misses a broader point: if I'm a freelancer trying to decide if I should write another pitch for Dragon magazine or maybe start applying to law school, the less opportunities there are to freelance the more likely I am to give up on the industry. WotC probably had its pick of most of the highly talented game designers in the industry. They didn't have their pick of the highly talented game designers who left the industry.JohnRTroy said:In the 1970s-1990s, you got designers who first worked on other games. The OGL can't be proven to directly be the reason for some of these guys being hired. The first quality is being a good designer and having talent. The OGL is irrelevant in this case. If there wasn't an OGL, they would have been hired based on either their work in Dragon or Dungeon or else from other game design work.
You also can't discount the benefits of training. Mike Mearls would have been a great designer either way, but you can't argue a Mike Mearls with 5 years of industry experience isn't better than a Mike Mearls without that experience. Do you really think the market for third party freelancers would have been as large as it was without the OGL?
