Damn. I'm 13, yet after I play GTA I have no urges to go out and repeat the actions I just performed in the game. Grand Theft Auto is rate Mature (17+), yet my favorite violent games are:
Grand Theft Auto series
Half-Life/Counter-Strike series
Halo series
All of the above mentioned games depict gross violence. In all of those games, the blood gushes from your enemies and is splattered all over whatever is behind them.
If Jack Thompson wants to ban the sale of M-rated games to those under 17, then they'll be added to the list of things kids can't buy, including cigarettes, alcohol, and pornography. But then, do games cause lung cancer, alcoholism, or chronic masturbation?
I also get all A's in school, am involved in many extra-curricular activities, and have a large social life.
