A couple of days back I stumbled upon a video by Matthew Colville. He’s your regular white, middle-aged, bearded geek with many years of DMing under his belt. He has worked in the video games industry and he has written fantasy novels. He also comes across as a genuinely nice guy and he has a lot of advice for anyone interested in running D&D – veterans and newbies alike. I’ve watched a couple of his videos so far, and I recommend you to check him out. I embedded one of his videos below.
By the way, if you know of any other YouTubers talking about D&D worth checking out, feel free to post about them in the comments below!
