I love critical hit. It's a D&d 4e podcast and there is so many stories and episodes I'm jealous of people starting it. Took me about a year to catch up. Even if you don't care for dnd, they tell a good and fun story. And they stay in character most of the time. It's a fun listen to.
I wish I could suggest more, but all I got is critical hit, bombcast, and wrestling stuff.
