Having watched someone else play most of the way through it, so far I think it’s actually a decent commentary on the subjective nature of morality, why we draw the lines where we do, and the real excuses we make to justify our actions. At least, a good case could be made for it. There’s some jokes about current politics, about organized crime stereotypes, and about the GTA series itself. Stereotypes abound, but whether they exist for purely juvenile reasons or to make the point that anyone can be scum could be debated. There’s some pretty funny stuff. There’s also some pretty screwed up stuff. Of course, I’m 24, I’ve had a few philosophy classes, and I’ve been known to use words like “post-modernism” without a touch of irony. I’ve got the context to make this judgment about it.
It’s very violent, very foul-mouthed, and very anti-drug and anti-prostitution.
[spoiler]The main character will drink, but you can drink and drive or get a taxi, and it’s almost impossible to control yourself when you’re drunk. The main character has a decided distaste for drugs and drug related crime. He won’t accept any offers of illegal drugs, but there is a mission where you go and pick up some coke for a dealer. The main character gets mad when he finds out that he was sent to kill someone just because the guy who was paying him was in the middle of a roid-rage. He’d apparently rather kill for other reasons, like “I don’t like this guy.” or “He fucked my cousin’s girlfriend.” or “This dude’s being blackmailed and payed me to do it.”
The main character can also frequent prostitutes, but has absolutely no respect for them, and makes comments after having sex with them about how he’s lost respect for himself. Despite this, I don’t think the game demeans women. Other women aren’t disrespected in the game and the female characters are just as strong and/or screwed up as the male characters.
[/spoiler] (Hence my point about subjective morality.)
It would depend on the 15 year old. Some might take the tongue-in-cheek asshole radio commentary to be the word-for-word opinion of the people at Rockstar, and some will be more savvy than that. FWIW, I watched *American History X * at age 16, in school, and while it horrified and disturbed me, it was overall an experience that taught me about the darker side of humanity.
GTA is a far cry from even a movie like Casino, which deals with similar issues, let alone something like American History X. I’d let a 15 year old play it, but I’d sit right there and watch it with him and make him talk about his opinions on the subject. I think playing a “bad” guy in a video game could actually be a useful teaching tool–how you feel when the game forces you to choose a side, the value judgements you must make, how you feel about violence after the game forces you to finish off a character who’s begging for his life. (This actually does happen, but he’s a drug dealer and an asshole…so is it ok now? No? Why?) I’m not a parent though, just a loudmouth young’n.
