5. Manhunt 2

Country that banned it: UK

The game originally fell foul of the British Board of Film Certification (BBFC) because of its "unremitting bleakness and callousness of tone". But bleakness and a callous tone never prevents Endemol from pumping hours of Big Brother on to our screens each summer, so we assume that the fact you're encouraged to gruesomely execute your adversaries with a bewildering variety of household utensils had something to do with it too. A High court Appeal eventually overturned the decision and the game was released to the satisfaction of bloodthirsty 14-year-olds across the country.
