Do you like beans? Do you like George Wendt? Would you play D&D with George Wendt? Do you eat beans while playing as George Wendt in a D&D game? Do you eat beans while playing D&D with George Wendt? Wizards of the Coast might not actually want to know the answers to those particular questions, but there are definitely questions about how you play D&D that they are interested in. They've posted up a survey that you can take now.
Note: They also ask about Magic: The Gathering. You gotta get through those questions first before you get to the D&D ones.
From the post:
We want to know what you think of D&D—and if you play D&D we want to hear what you have to say about that too in our latest survey.
