Gunpei Yokoi is one of Nintendo’s most important designers, having been the mind behind ideas like Metroid, the Game Boy, and the Virtual Boy. He left the company in the 90s and was sadly killed in a car accident shortly afterward.

In a new deep dive video, Did You Know Gaming examines Gunpei Yokoi’s life and death. Specifically, they delve into the online conspiracy theory that Nintendo was somehow responsible for his accident. Their ultimate conclusion is that there’s no evidence to support this theory at all.

The video includes the results of research from various interviews over the years, as well as newspaper reports from the time of the accident. This is the third video in Did You Know Gaming’s Gunpei Yokoi series following their histories of the Virtual Boy and the Wonderswan.
