I suggested they could try to get likeness rights to celebrities who've played D&D to do as their characters. I've seen too many people say they wouldn't pay $30 for a Patton Oswalt, Stephen Colbert, Felicia Day, or Wil Wheaton though. I think monsters are where the appetite exists but that's also where the tooling budget is heaviest. Honestly, they might do better licensing D&D to McFarlane. He already does Critical Role.
