From the description:
Oh, man! I'm so excited to finally have Jon Van Caneghem, creator of Might and Magic and Heroes of M&M on the show. This will be a 2-parter. In the first segment, Jon plays his awesome new game Creature Quest and talks about the mobile scene and why he's so jazzed about it. The following segment will cover some history of his company, New World Computing, and various design philosophies.
Around 23:20, Matt mentions he'll be interviewing Tim Lang within the next few weeks as well.
