Factory Sealed is an audio podcast from ManaTank.com which usually features talk specifically of retro games and retro gaming. It can be conversational at times but, that is not a bad thing since the hosts and participants are entertaining. Every episode they agree to play a retro game and discuss their impressions of it on the most current episode. However, it is hard to say when episodes arrive in your feed, recording and posting does not seem consistent as of yet.

If you haven’t already seen his stuff or if looking through the roots of computer gaming without a Wikipedia page is something you’ve been yearning for, indulge in the plethora of videos from Lazy Game Reviews.
