I’m a big fan of Matt Colville’s Youtube channel.
I like the Acquisitions Inc. sessions. I’m not current on the C Team series, but I’ve watched some and it’s entertaining.
I like Dice, Camera, Action. Perkins is just a good DM, and those players have really grown on me.
I’ll also second the mention of Roll Play. Adam Koebel usually makes for an interesting game. I’m haven’t watched all the series, but a bit here and there, and I like the one-shots. They’re a good way to get an idea of what a game is about.
