I'm not sure where you live, but here in North America violent crime rates have been falling pretty steadily. So I don't think you can argue that society is becoming more violent. The most linked causes of violent crime are poverty and youth. Since the population has been getting older and richer, society had been getting less violent, not more.

As to sexuality, I would challenge you to argue that sexuality is somehow inherently immoral. I doubt you'll be able to do so without logical fallacies. I have no idea why pictures of naked women are more offensive to Western society than graphic murders. Nobody has ever died from boobies.

The world is definately becoming more free with things that used to be taboo, unlike ssj12 I think this is a bad thing, in that, we have created a society (at least in the Americas) that is solely conserned with pleasing oneself without regard to consequences or responsibilities. Anyone who thinks that increased sex with multiple partners or wanton violence is a good thing obviously hasn't thought about the results of these things.

Teenage Pregnancy, the spread of incurable STDs, school-shootings, rape, armed robbery, and other violent crimes are directly related to the increase in instances of these acts portrayed in the media in general (not just video-games, and movies). All of these things listed above have increased dramatically in America and have done so ever since advertisers and media outlets stopped self-policing themselves and began releasing more contraversial material and IPs while standing on a podium of free-speech.

I don't believe the media to be the sole cause of the increase in unsafe and violent practices however, and before people start flaming me, it should be know that I personally don't have a problem with any of these things, nor do I object completely to questionable movies, video-games and advertisements. I do have a problem with people not talking to their children about sex, and violence in movies and monitoring what they are exposed to. By acting like it's not a problem, they run the risk of their children becoming disturbed by these images to the point where they act out, or participate in unsafe behaviors.

People are not going to change what other people do on a massive scale, but you can change the world around you by making an effort to change what you can. People in America are just too damned lazy to try, or they want to pawn off the responsibilty on someone else. Who in all likely-hood never marketed their product to Joe-Psycho-fifteen-year-old in the first place.

EDIT:

@Famousringo I don't think sex is inherently immoral, however, many of the reasons not to have sex with multiple partners are sound advice and should be seriously considered as a reason NOT to be sexualy hyperactive. In the same vien, pornography has ruined many relationships and should be considered taboo for anyone in a relationship where devotion is expected (unless both partners enjoy it of course).

There are also many studies that show the presence of two parents in the household is important for the stable development of children. In fact, one study done on convicts in the penal system, discovered that almost 80% of inmates had no father figure in the home while growing up. This is a huge problem that only becomes more compounded when wholesale sex with multiple partners becomes normal; at that point no one wants to be monogomous; marriage is treated as a joke and as a final death-knell to the freedom to bang anything you want. I think that does more damage to children and creates more criminals than all the images of violence in every video-game Rockstar produces.

It seems like very generation in video games, there are more quality games that focus mainly on violence and sex. There have pretty much always been violence and sex in games- in my opinion the quality and quantity of these games began to rise in the Snes era, and have not stopped. We are not at the point where you can simulate virtual murder by going through motion sensitive murder gestures that initiate gruesome murders on your TV. Whats happening to gaming? Whats causing this?

I have a couple guesses, and none of them are mutually exclusive.

The first is that, as video game graphics get better, it is easier to represent sex and vilence in games. For example, GTA was portably not possible until last gen.

Another guess is that people are just curious about violence or aspects of violence, and are trying to understand it. This could be especially true in games such as Call of Duty.

Yet another guess is that society in general is become morally corrupt. For example, there is a banner add on this website that has a partially naked woman. No one, including myself, thinks anything of this banner I bet. IT's just the way it is. Perhaps that is happening with video games as well; as violence and sexuality become more accepted in society, these ideas become more prevelant in the game.

My last guess is that the number of violent and sexual games is increasing because there is a market for it. This on is pretty obvious though :P

Please note that I am not for banning violent or sexual video games, though I am morally opposed to games such as Leisure suit Larry: Magnu Cam Laude or Manhunt.

What do you think is causing the increase in sexuality and violence in gaming?
