"I wanted to become independent."
Gunpei Yokoi is famously known as the man behind the creation of Nintendo's massively successful Game Boy. He also ended up working on the Virtual Boy, which is considered Nintendo's biggest flop to date. Shortly after the release of the "VR" headset, Yokoi had left Nintendo to pursuit other interests. The prevailing theory was that Yokoi was asked to retire due to how colossally awful the Virtual Boy performed, but that turns out to have been just an assumption.
