I picked up Dungeon Mastering in 2018 after a 20 year break and the amount of quality helpful videos on Youtube really took me by surprise.
Fast forward to 2020 I regularly get asked what videos I recommend new Dungeon Masters should watch, so I went ahead and created a YouTube list of videos in the order I found them useful to watch. This point is important as they jump between different content creators.
It’s also important as I don’t suggest you binge watch the whole list. Just start from the top and stop as soon as your writing finger starts to itch.
