Critical. Role started as a group of actor pals playing Dungeons & Dragons while a camera rolled on Twitch and YouTube. That unlikely start has become a huge Kickstarter hit, raising $7.7 million and counting to create an animated series called "The Legend of Vox Machina,"  based on the story lines and characters of the long-running games. I sat down with Sam Riegel and Travis Willingham, two leaders of Critical Role, to talk about O.G. D&D (that's me), creating an unlikely cross-platform media machine, and what they're going to do with all that loot to make a great animated series that will run....somewhere. C'mon, roll the dice. Give it a listen.
