Well like Vagrant said, some can't make the distinction between a game and reality. In some cases, that comes from either a lack of knowledge about the subject or a psychological disorder and some of those people are highly impressionable. Somebody plays...say Postal 2, and finds it unbelievably cool to stick a cat on a shotgun, so gets his family cat, gets his dad's shotgun and plays some RL postal! I remember reading a newspaper article about some guys that were so into the Matrix, that they dressed up all leather and coats, packed a ludicrous amount of weaponry and stood in the middle of the highway, blasting away at cars. Video games are, by all standards, the paramount achievement of escapism. Who wouldn't want to be a medieval hero, swinging his shiny sword around, destroying evil and hoarding massive amount of gold and jewels? Problem is, for some people simulated environments provide much more pleasure than reality, which is their fault, as much as it is the fault of the society that provides confusing and often multiple standards for socializing, entertainment and the pursuit of pleasure and happiness in whichever way. Edited a bit :P
