This shows how sick video games can be and why there should be a tight control over their contents if we do not want our kids to be infected by them.
Even when video games have no shocking contents, they do not have good effects on children anyway. It's better for them to do sports or play music, for example.
The game was never designed specifically to kill Jews but that's not to say there isn't anti Jewish themes in the game, i've played Grand Theft Auto and it's a very sandbox type of game, you pretty much roam a city with a bunch of pedestrians and there are certain ethnic blocks including areas with Jews. In one part of the game, you do fight what is called "The Jewish Mafia" who are diamond traders at one point in the game and they are very wealthy.
In the expansion for GTA IV though, you play as a Jewish biker gang member. I think the idea of GTA was just to offend everyone kind of like South Park.
Granted I am a bit confused why Jews were put in the game but yet you can't find a single Arab walking the streets in Liberty City.
