History was made with these entertaining and addictive, beautifully designed artefacts...Electronic handheld games.

"Game & Watch is a line of handheld electronic games produced by Nintendo from 1980 to 1985. Created by game designer Gunpei Yokoi, each Game & Watch features a single game to be played on an LCD (Liquid Crystal Display) screen in addition to a clock and an alarm (thus, 'Game & Watch').
Gunpei Yokoi, traveling on a bullet train, saw a bored businessman playing with an LCD calculator by pressing the buttons. Yokoi then thought of an idea for a watch that doubled as a miniature game machine for killing time." -Wikipedia


My nostalgia collecting mania was triggered by this book:

Electronic Plastic, 2000. www.handhelden.com

Here you can find some cool G&W emulators (!): www.zophar.net/gw.html,
and this is the most complete handheld database: www.handheldmuseum.com (it's worth its name).
And finally, the blog of a fanatical collector: www.balduin.wordpress.com/category/game-collection.
