I somehow agree with Styish Executive's post. 15-16+ realize that the scenes in video games don't exist in reality and they shouldn't be taken serious.
But speaking honestly, I played video games like Grand Theft Auto series, Bullworth Academy and those like Medal of Honour at the age of 12-13 At that time I use to think myself as a street gang member in future and doing these tricks. Later I realized that its bad and all but yeah it might provoke someone else to like these things. Some of these games do promote violence like those being produced by Rockstar games.
