The primary thing Wizards wanted to promote at this event was their upcoming virtual tabletop for playing D&D on computers. Virtual tabletops are not a new concept, but they want to create a fully integrated, fully monetized experience that no one else can compete with. This was part of the reason for the OGL uproar that happened in January, when Wizards/Hasbro tried to nullify a 20-year-old binding license agreement that allowed third parties to sell D&D-compatible content. They don't want other virtual tabletops to offer people alternatives. They want all the players integrated, and all the money. They have poured 300 million dollars into this project, and it must succeed.
At the summit, they showed it off again and of course it looks quite nice, Unreal 5 and all that. One YouTuber asked about the pricing structure, how much are things going to cost, what sort of things are going to be sold, and they deflected. "That's a question for the business department, not me." Someone else asked what kind of specs would be required for this nice-looking software, and they said they didn't have it pinned down yet. Creators pointed out that with it looking as good as it does and running on a custom Alienware machine, it could turn out prohibitive to stream alongside it. The Wizards rep acted as if this was brand new, mindblowing information and said they'd have to take that into account now that it had been revealed to them.
At this point, one creator sperged out and gave them a dressing-down for several minutes, more-or-less saying "if you're not going to tell us anything about your upcoming product, then why the fuck are we here?" Others took this as a sign that the vibe in the room had changed, and the audience turned on them, taking the opportunity to start asking hard questions about other things. Ways that Wizards was running the business poorly and ruining D&D. The hosts stammered and struggled and tried to deflect. Everyone wanted to talk about the January OGL debacle. Wizards of the Coast actually held a poll among everyone at the summit asking whether everyone wanted to see more cool new announcements, or get into the weeds about the OGL controversy, and unanimously everyone agreed they wanted to have a sincere talk about how shitty they've been recently as a corporation. It was a trainwreck of a conference.
Ultimately this is their own fault for completely misjudging the kind of people who cover the tabletop gaming industry, and expecting to be able to hold a light, breezy PR event like other companies do without any pushback.
