Arm Spirit, a Japanese arm wrestling arcade game, has been recalled after breaking the arms of three players. From the Associated Press:
"The machine isn't that strong, much less so than a muscular man. Even women should be able to beat it," said (game distributor) Atlus spokeswoman Ayano Sakiyama, calling the recall "a precaution..."
"We think that maybe some players get overexcited and twist their arms in an unnatural way," she said.
