Ever want to play a game that can break your arm? Well, here's your chance. 1992's Arm Champs 2 features a mechanical arm that can arm wrestle with a player at the drop of a quarter. Unfortunately the game could be configured to unleash the ultimate power of machines and break players' arms in mere seconds, snapping bones into pieces. In China, for example, one store that offered the game as a diversion reported over a dozen injuries in the first few months the game was available.

If you should have a death wish one can find the game for sale (typically used) for around $2,000. It was originally manufactured in Japan for the Asian market by Jaleco with warning labels about the game's strength printed in English.
