Having fun with the World Wars...

Call me an old fart, but I find it shocking, video games which are taking place during the first or second World War. How can people have fun and entertainment about such dramatic events?! I am talking about the first "Call of Duty" games, or the upcoming "Battlefied 1". It makes me sick. I think that youths are totally disconnected from the reality and that video games are making people totally insensitive.
