Sonic the Hedgehog can have his own podcast because there have been 14 main Sonic games. There has been a Sonic game released every two years for two decades. At any given moment, there is a Sonic game in development.
There have been 4 main Oddworld games. The last one came out eight years ago. You wouldn't be able to make a monthly ten-minute podcast unless the theme tune was nine minutes long and you talked really slowly.
