The Virtual Boy is known as one of Nintendo's greatest failures. It took a lot of years for Nintendo to embrace that failure and have fun with it, but today we learn that it was almost SEGA's failure to deal with. Turns out SEGA was keen on working with Reflection Technologies, the company that provided the tech behind the Virtual Boy. SEGA even had a working prototype of a device that provided pseudo virtual reality, but the problem was everyone that used it felt sick afterwards. SEGA decided to move away from the idea, which obviously paved the way for Nintendo and the Virtual Boy.
