Some have gone very far to persuade their children against that game. Think about this Swedish father who took his sons to a war zone to show them what war was really like. I read it on the newspaper, but cannot find it now. Until then, there is a reference on this link.http://www.giantbomb.com/forums/off-top ... 67/?page=1
I would definitely ban the game at home and have a good talk to my boys about it. They may feel left out, which is unfortunate. However, I hope they can find other things to share with their friends. In the past, they have felt left out as I have never bought them a toy gun or sword. They have played with them at their cousins and I am not going to lecture other parents. Most boys play with toy guns and don't grow up to be criminals, however, maybe I am wrong, but I will err on the side of caution.
Screen time is one hour at our home, which includes any type, such as TV or games. The computer is in our living room where we can see whether what they watch is suitable.
Good luck, I know how they can put pressure on parents!
