To say that I'm underwhelmed is an understatement. I know that WotC has marketing people. I know that Hasbro has them. This is a fantastic opportunity to get media attention about the game and free promotion like you couldn't believe. So far do we have any marketing?
Off the top of my head, running a series of interviews with people who've been playing the game over the decades, working with the many celebrities that play the game. Have short videos that have them saying "happy birthday D&D" at the very least. Highlighting the popular culture impact of the game over the decades. I know people have been talking about Disney, but for a company that does things right, Disney lives on nostalgia and it makes them tons of money.
If I had to guess, it's because the people who are doing marketing for Hasbro, and likely D&D as well, know nothing about the game. But at least you would expect them to be able to say "we have a big brand that has a 50th anniversary, let's make some noise."
It's truly sad because this is the last big anniversary I'm likely to live to see and so far there have been crickets.
