Garbage in...Garbage out, I won't allow it in my household either. The games I allow my sons to play is limited & rather benign. It really doesn't matter whether it is real or fantasy, I believe it effects them emotionally, I have seen it. Would you allow your kids to play "Grand Theft Auto" ? Gratuitous killing, stealing, virtual rape? I don't think that a case could be made that these things edify in any way, in fact they oppose the values I intend to instill in my sons that will some day be men.
:up: I don't know which games are what but I would not play games that are as you described. I do play zombie shooting games and I would have no problem with a game where you are only rewarded for killing the "bad guy".
