I'm thinking WotC believes this as well.
And that's the thing that has me all bent out of shape.
To me, the game is more important than the brand. I have more positive memories of making up stories in a room with a bunch of fellow nerds than I do of reading D&D novels someone else wrote by myself. I have more positive memories of my friends joking around through a campaign than I do of Chris Pine's charming smile. I have more impactful memories of character arcs and stories from people that changed me than I do of any TV show of any genre. Not because of the brand of D&D, but because of the game of D&D. That's the thing I want to teach my kid, that I want to introduce newbies to, that I want to share with people like me, to make a connection over this weird little game.
The game means something to me, and it's being blown up because it means less to WotC than the brand does. The brand doesn't mean much to me. The stories I made with my friends will always be more meaningful to me than the stories Wizards made up that didn't involve the characters and villains my friends and I built.
