Episode 1 does regular campaigns (sometimes with Felix as a guest), mostly in DnD historically, but somewhat recently they started running a CoC campaign that is now like a third of their campaign catalogue I think. I'm not sure, I dropped off their patreon before it started, but I definitely want to sneak on one more time to get it.

Edit: I forgot to say, maybe the two of them could collaborate here too, with Will helping Branson write or something so it's appropriately engaging.
