This type of publicity is good for the game.  Hopefully, the publishers will capitalise of the media coverage, without being crass.  I suspect this game will serve cathartic purposes, more than it might be detrimental.  Wars instigated by Western nations, have been distant to peoples in these countries.  I expect Six Days in Fallujah to bring home some of the flavour of those questionable, and distant wars, to largely, indifferent populations.
