The Gaming Historian channel on YouTube is one of my new favorites. The channel has been dispensing quality retrogaming videos for years, so I've enjoyed diving into their catalog with my recent discovery. The channel's latest documentary is a comprehensive history of the short-lived Power Glove controller released for the Nintendo Entertainment System.
The Power Glove was really the first mass-marketed virtual reality device and this 27-minute documentary follows it's development and all the way through it's subsequent downfall. I really enjoyed it and retrogamers should as well.
