What I hate about Jim's argument, and though I will admit he has some very valid points is that he doesn't really seem to get the context of the game of School Shooter. The big picture is, you, the person with the gun, are charged with the task of killing innocent "school-children" in a school setting, and that IS unnerving no matter if you compare it to war games or silly GTA games.
GTA's context has a social standing point, and takes lots of shots story wise at Mafia relations and drug abuse, and in any other setting, if it were a more serious game, would be very depressing because the characters in the game are so down-trodden and so low on the social and class scale that they have to scrape to the "top" and the "top" is so criminal that it wouldn't even justify being a higher class than when they started. BUT because it's GTA, you run over old ladies, you do crazy car stunts simply because you can, and the jokey, cartoon like setting and the characters total disregard for any harm to them or others simply reinforces that. It's FUNNY in the context of the game's silly humour.
School Shooter doesn't have any other point, doesn't exist in any other context other than being exactly what it is, a shoot-up in a school setting. It's exactly the same as if someone made a mod of the player manually crashing a plane into the Twin-Towers or the Pentagon. You're playing the bad-guy and your role is only to do what the game tells you. Perhaps, if they had put in a little depth into it, maybe tried to empathise with the shooter a little more the gaming community would have understood, because looking at a tragety from all angles including the perpetrator's gives alot of insight.
But they didn't; they made a mod, at the end of the day, where you shoot "children" in a school setting. I'll admit they didn't try very hard, in fact they barely tried at all, and what infuriates me most is that they put so little effort in to empathise with it all, and in the end defend their right to make such utter tripe simply because they wanted it to be offensive. Fannies to that I say.
