The Japanese have come a long way since Space Invaders. The latest craze to hit the arcades in Tokyo is Boong-Ga Boong-Ga, whereupon a player can select from a variety of foes and then proceed to, er… spank them. Amongst the choice of targets are “ex-girlfriend”, “prostitute” and “child molester”. Upon completion the machine will issue you with a card that’ll explain “your sexual behaviour”. In my humble scientific opinion, this is well-and-truly fucked-up.
