I’ve been doing the Space Quest Historian podcast for 3 seasons now. It has featured input from Space Quest alumni Scott Murphy, Mark Crowe, Ken Allen, Josh Mandel, Mark Seibert; Space Quest III composer Bob Siebenberg; and (in season 3) the developers of Fran Bow, Shardlight, Scratches, Darkside Detective, Dropsy the Clown, Blackwell Epiphany, and more.
Subscribe to the show via iTunes, Android, RSS, Stitcher Radio, or whatever you want.
I have two other podcasts with mates of mine. Look for links to those in the footer.
