(WVLT) -- There's concern about a new version of Grand Theft Auto out Tuesday, and the Washington Post says the video game has all the hot buttons: intense violence, strong language, use of drugs, sex, and nudity. Worse yet, even if you don't know about it, your kids probably do.

Grand Theft Auto IV is a game where you play the bad guy who steals and commits crimes to win.

A local child and adolescent psychiatrist says not only should children not watch such games, but also questions why any adult would want to.

He says the desensitization is just like what the military does to train troops to go into battle.

Grand Theft Auto 4 hit game store shelves today and some say it could break sales records.

But some are asking why? The game has nudity, strong language, strong violence, even alcohol and drug use. Some police groups have expressed their concerns.

Alcoa Police Chief Ken Burge says, "I think people really need to be cognizant of the fact that this game could desensitize them to the sex, to the violence, make them more aggressive."

A Knoxville child and adolescent psychiatrist agrees. Dr. John Robertson says watching such realistic games can have a negative impact.

He says, "There's a line between we think about something and then we plan to do it and we act upon that and that line gets more and more blurred is what's happening."

But Roberson feels it can have an affect on those besides children.

"Yes, they are for mature audiences but why would adults even be playing them. I have no idea."

Robertson says the games reward bad behavior, which is how you win the game.

"You get rewarded for going to the prostitute. You get more health benefits, and then if you steal her money, beat her up and steal her money, you get more."

The doctor feels it becomes more detrimental the more someone plays such games.

"Just going to church on Sundays isn't going to necessarily negate hours and hours of raping, pillaging, and murdering."

Robertson feels there's a big difference between rewarding for bad behavior and the days of Superman, Batman, and G.I. Joe.

"There was morality. There was a sense of justice. There was a sense of right and wrong in that. They have totally flipped that."

The video game industry expects Grand Theft Auto IV to sell six-million copies totaling $400 million in sales worldwide.

If the trend continues, experts believe it could break the record held by the game Halo 3.
