The Vectrex may be the most innovative video game console you've never heard of. It had everything it needed to prompt a revolution, including controllers far more sophisticated than the competition and the ability to render polygons a decade before gaming's 3D revolution.

It was years ahead of anything else on the market, yet it could not have launched at a worse time. The Vectrex hit stores at the tail end of 1982. Over the next six months, the then-booming video game market went bust. The Vectrex, a potential revolution in home gaming, was swept into bargain bins, forgotten by all but the most ardent of collectors.
