3d6 Down The Line
Jon Britton
3d6 DTL is a tabletop roleplaying game actual play series, with a focus on the Old School Revival (OSR) of classic Dungeons & Dragons and its simulacra. We have none of the ego-facing, performative aspects, but all of the easy rapport displayed naturally by a group of old friends. Listen to how D&D is actually played!
