What is the fine-grained topic of the following text: Little did I know that Tony himself was the designer of the excellent “How to Host a Dungeon” solo game, which has been a driving inspiration for the initial direction of my Old School Hack design – a sort of “Adventure Builder Toolbox” package for nostalgic Dungeon Masters, though it’s pretty clear right now that I need to put the horse before the cart and focus on the fundamental rules presentation first. Only return the topic.
