There is one guy, who has tried to sue Rockstar on almost every game they make... Can't remember his name right now... I'm sure someone can help me out...
Well anyway, he lost every single case. All his cases were saying that games like Manhunt and GTA were causing kids to go out killing. In one case, he tried to blame a murder on Manhunt. Well, the murderer had never even played a PS2, the victim it was found had played Manhunt.
