The Green Hermit
Hero
My players and I all started with nothing but the Essentials and the core books. We had seen zero streamed games. A lot of people don't waste all of their time on Youtube, especially those who like to do tabletop games.That's less important
Think most people coming into the game will have seen one or two streamed games and have an idea of what is DnD
And those descriptions weren't very useful. You already needed to buy a $50 book to read them
