A couple of excellent examples of my serious Dungeon World game play come from the Gauntlet RPG community podcasts.
At the end of most Discern Realities podcasts, you can find a one on one actual play snippet between the hosts. https://www.gauntlet-rpg.com/discern-realities
Jason Cordova, head of The Guantlet, also has an ongoing Dungeon World campaign actual play called We Hunt The Keepers (though this may drift more towards World of Dungeons). https://www.gauntlet-rpg.com/we-hunt-the-keepers
