I'm so glad I stumbled across his videos a few weeks back. He is really quite inspirational in terms of encouraging viewers to jump into DMing. Having done it way back in my teenage years and just getting back into the game, it's daunting to consider, "Can I do this right?" and his tone is so positive. I love his appreciation for the history of the game too!
I have been playingsince 3.5 on through now and had always been a player. I tried dming twice but it never stuck. Recently Itried DMing and his videos have made me much more efficient and eager to keep the adventure going. Highly recommend Matt's videos.
