The board game Operation is a great example of how negative feedback can also negatively affect your performance. But instead of playing in constant fear of that loud buzzing sound, when you touch the sides while playing this sadistic version of Operation, you get blasted with a paintball gun. Sounds like a lot of fun.
Madcap Brothers’ modified version of the game gives each amateur surgeon a minute to remove as many body pieces from the patient as possible. Except that the fear of getting a paintball in the back probably makes it all but impossible to keep your hands from shaking during the make-believe procedure. But it’s better than a modified version of Monopoly where you get shot at every time you land on a property with a hotel. [YouTube via Geekologie]
