The giving characteristics in many games makes it almost impossible to personally get into the game. Yes it might bring your eyes and mind to attention but can you really go around saying that you have a new hobby, or go talk to your parents of the accomplishments you have done? Not really, violence I can see a better opinion on, it kind of gives you the out of body experience of doing something you wouldn't do on your own, and settles the urge to find out in real life. However sex, it is only a trick to gain viewers and or cash, everything is mentally disturbing and I believe that sex in games are more likely to influence the user than violence and often brings personal urges of those influence to do the same to others in the same situation as the game. It is also the fact that they portray the other gender as being easier than that actually are in real life, so its not only a bad thing but it also causes you to be in a disadvantage in your true experience of what you see in videogames.
