Spoony is a satiric game and movie reviewer, tied in with the likes of The Nostalgia Critic, The Cinema Snob, and The Angry Video Game Nerd.
But his most popular feature is Counter Monkey, a series where he recalls tales of the tabletop, and gives advice for game masters on how to run an effective game.
This is an excellent resource for both worldbuilders and tabletop game designers. Not only does he give direct advice for players ("Don't get on the boat") and game masters (Run a Star Wars game with "All Jedi or no Jedi"), but his tales about both better-known and lesser-known games can inspire creativity and imagination.
Even if you're not a role-player or have no interest in games, his discussions on character motivations, tropes, villains, and the like can offer a lot for worldbuilders with a focus on plot or characters, as well as descriptions of monsters, settings, and even diseases can aid in creating diversity for a world, and introduce new aspects of worldbuilding you might not have considered.
As I submit this, he has 67 posts, some of which are hours long, so there is tons and tons of content to soak in. You may want to start from the beginning (which is at the end, currently page 9) and archive binge. From the very first video ("Shadowrun: The Squirt Gun Wars") you'll get unique, hilarious, and creative takes and tales on all kinds of worlds and games.
