Game & Watch

It was Gunpei Yokoi who first came up with the idea of producing LCD games that would fit onto a unit around the size of a pocket calculator. The Game & Watch titles could run on a single watch battery, and not only told the time, but also provided simple-yet-addictive gaming challenges.

The Game & Watch games were a runaway success the world over, with many titles selling over a million copies. Sixty Game & Watch games were released over ten years (though some were doubles of earlier games). There were also Game & Watch renditions of Donkey Kong, Mario, and Zelda, each complimenting their NES counterparts. Nowadays the Game & Watch systems are highly collectable, some fetching hundreds of pounds on auction sites.
