Tunnels and Trolls is kind of on the roleplaying fringe. A tonne of people have heard of it, some may have even played it, but there's very few people actually talking about it. There are at least a billion OSR podcasts out there and nothing for T&T (I attempted once, but failed to keep up).
Thankfully one Peter Seckler has launched Werewolf Blood, a podcast all about Deluxe Tunnels and Trolls. It's just released its second episode (the first was a short intro), which you can find here: m.soundcloud.com/werewolfblood/wb-episode-2?utm_source=soundcloud&utm_campaign=share&utm_medium=googleplus
Put Peter's delectable tones adjacent to your eardrums (along with some sweet bluesy riffs). I order you.
