Friends at the Table is the best podcast.

It's an actual play podcast run in game systems designed mostly for story generation, operated by people who who know there's no such thing as a monster, and I'd never seen anything like it.

They ran some seasons in a post-fantasy-apocalypse world, some in a Star-Wars-meets-Gundam science fantasy world, and one recently in a Western sort-of-horror setting. I started at the beginning, with Autumn in Heiron, featuring orc archivists who work magic using extremely specific shopping lists, undead pastry chef boyfriends, and an "evil" alignment of "destroy something rather than trying to understand it".

But for the impatient you can start with Marielda. Marielda is a series of heists by a crew of illegal knowledge dealers, in a fantasy city that sounds like New Orleans, patrolled by living statues and ruled by a god who forged the sun, whom our players proceed to fight.

The sci-fi side, which is running its fourth season now, starts with COUNTER/Weight, a game set in the aftermath of a mecha movie never made. It features a character who is "what if Han Solo used to be Beyoncé", psychic hackers, and mechs who might be gods.

Also there's no sponsors because the GM is too punk for that.
