GTA V is a game where a big part of it is about playing like a gang-criminal. It is about making crimes for money. Its fictional ofcourse but even the police are being represented as enemies of the gang. I do think that this game is bad for the moral of the gamer playing this game. When its comes to the discussion about video-games/pc-games creating bad behaviour. I am afraid that they can do it. So the pc-game LA:Noire is probaply a better choice because I have read that you play as a law upholding policeman there.

To try to see the moral of the main characters in a game is important when thinking about playing a pc-game/console-game.
