I am not against games, as I am playing some games.
But neither the idea of "art" nor the imagination of "truth" free the creators from responsibility for the contents.
I am willing to see severe brutality, if the presenter shows it with the intention of information and with a heart and empathy to the involved souls. And I am disgusted with brutality shown with the intention to gain attention and without any feelings to the victims or offenders. There I don't make a difference between videos, games or other media.
And if there some gamemaker stand up for there "right" of making art and handling "the truth", the question may be allowed, whether they want to prepare children for becoming soldiers in inhuman wars.
In Fallujah per example not only a very low number of americans died, but e very huge number of innocent iraqi citizens without any chance of escaping the inferno. The real numbers of the victims of falujah is not reported in most media. If the game would enlighten the truth by showing it with empathy, I would like it. I assume, that it shows only the clean view of the american de-facto agressors without any heart with the innocent civilian victims.
