They still propose the stories, edite the adventures and publish them. They have WotC stamp all over them. Heck, all the guys at Sasquatch Games are ex-WotC employees. At Kobold Games, it was ex-WotC employees with good rep that screwed up Tiamat.
Okay, but what are we talking about here? Are you suggesting that no one who has ever worked at WotC can write a good adventure? That they are all somehow tainted? Because that knocks a lot -- and I mean a LOT -- of RPG companies out of the running, including the folks behind both Pathfinder and 13th Age.
It certainly boost confidence in WotC.
I'm not sure I follow what you're saying.
Or when you do not know what to do anymore. Look at Hollywood and all the remakes.
Actually, a TV series is the medium like the is the medium. The X-Files is the adventure, the theme if you prefere. Doing a X-Files reboot only shows how much they can't innovate and just recycle stuff.
To quote Stuart Bloom from The Big Bang Theory, "Okay, if you're gonna question the importance of an actor's signature on a plastic helmet from a movie based on a comic book, then all of our lives have no meaning!"
Dungeons & Dragons is Dungeons & Dragons. That's not to say that there can't be original thought in D&D products, but without the recurrence of certain themes, original fantasy is just original fantasy, not D&D, and some of us, at least, are here because we are /fans of D&D/. Not fans of fantasy roleplaying, but fans of D&D.
I can and often do develop my own fantasy stories and gaming supplements that have nothing to do with D&D lore, but why on Earth would I want to buy a product like that from someone else? I'm here for the themes. Remove the themes and it's just someone else's fantasy setting, and while I'm sure you are all brilliant people, out there in ENWorld, for the most part I could care less about your ideas. It's not personal, it's just that I'd rather use my own.
But D&D, like any other entertainment brand, is different. It has 40 years of history, stories, characters, and worlds that are a shared experience among its fans. Furthering those concepts to increase the volume of material available to those fans is not a sin. It's not even recognizably flawed as a strategy.
And what's more, and what I think Wizards is finally starting to realize, is that fandom is to some degree self-sustaining. Capitalize on that shared experience, and it brings new blood in on its own. Geeks are curious, and as they pursue the answers to their questions they become fans.
