DMs Guild creator and game designer Matthew Whitby pops in on in the podcast. In addition to being a creator on the DMs Guild, Matthew is also working towards a Ph.D. in game design. Matthew enlightens us all to the "door problem" in D&D and other TTRPGs. We dive into game design and cross into some philosophical territory as well. Matthew gives us his best GM tips and tells us about publishing on the DMs Guild. Plus we talk about his RPG interview show on YouTube called the Dungeon Master's Guild House.
