These range from TV shows, like indie streamer Dropout’s Dimension 20, to podcasts like Dungeons and Daddies and Not Another D&D Podcast. Brennan Lee Mulligan has GMed over a dozen seasons of Dimension 20, from Fantasy High to Cloudward, Ho! He also GMed Exandria Unlimited, the Critical Role anthological series of minicampaigns, so he has experience with the series already. He has also signed a three-year deal to develop more seasons of Dimension 20, so it won’t mean any less content over on Dropout. Critical Role: Campaign 4 begins on October 2nd, 2025, on Twitch, YouTube, and on Critical Role streaming service Beacon.
