Retronauts is an interview- and panel-format show about video game history, with episodes hosted or co-hosted by Stuart Jipp, Nadia Oxford, Bob Mackie, and John Linneman depending on the topic. Panel episodes bring multiple hosts together to unpack a single studio or genre in depth, such as a retrospective tracing Shiny Entertainment's run from Cool Spot and the Genesis Aladdin through Earthworm Jim, MDK, Savage, and Messiah. Other episodes are direct interviews with the people who made the games under discussion, including indie developer Mike Hommel of Hamumu Games, discussing Dr. Lunatic Supreme with Cheese, Growtopia, and Kid Mystic, and Mark Pierce, creator of the classic Mac game Dark Castle and its sequel Return to Dark Castle. A two-part series interviews Sonic fan-game and hacking-scene figures Ryan Langley and Lewis Clark about how community tools like SONED and hacks like Knuckles in Sonic 1 fed into Sonic Mania and later official ports. The show also turns to game-adjacent culture, including an episode built around host Nadia Oxford's own experience of 1990s Mega Man fan fiction and BBS-era online fandom. Recurring subject matter includes studio and engine technical detail, ROM hacking and fan-game preservation, indie development stories, and the history of online fan communities. Some full-length episodes are exclusive to Patreon subscribers at the $5 tier, with the public RSS feed sometimes carrying only a short preview and subscription pitch rather than the complete discussion. The tone is educational and conversational, with hosts citing specific technical details (sprite tricks, hardware limitations, tooling) alongside personal anecdotes from guests. Listeners drawn to detailed studio and franchise retrospectives, developer interviews, or fan-driven modding and hacking scenes are the core audience, more than listeners looking for new-release reviews or news.
