Occasionally terrifying but often interesting video game forum selectbutton now has a podcast! Every episode is edited by a professional audio engineer, so it sounds pretty decent for a show conducted via Ventrilo, of all things.
I was in episode 2, which covered fighting games in a less-accessible way than I would have liked (there is some irony in there, I'm sure), and episode 3, which was marred by technical difficulties and a questionable choice of topic.
Episode 4 (subject: the treatment of video games in other media) features the guy who made the smmooooothest Let's Play video ever made as host, along with a really well-researched and coherent discussion from all the guests. Good place to start listenin', I'd say.
The show's also on itunes, and I'll be sure to make a post or two here when I show up in future episodes.
