What is the most brutal videogame in gaming history?

[Airaku]

Mad World, No More Heroes, Man Hunt 2, Soldier of Fotrune, Postal, Ninja Gaiden.

Are you looking for violent games to play? You sick twisted fuck! Hahaha I'm kidding. Most of those are actually good fun games. I am pretty fond of No More Heroes and Ninja Gaiden 2 in particular.
