Seems like it's been shelved, for just a bit atleast.
Doesn't seem fair, does it? You violently kill people, is that the reason? Well, that's a bit hypocritical. In shooters, you shoot people. Shoot them enough and they die. You've killed rather violently. In F.E.A.R., soldiers can explode into a bloody mist of gore, so why is it any different here? In Jedi Knight, you can slice off limbs. In Oblivion, you can smash that enchanted daedric warhammer of yours into their dead, lifeless faces for as long as you like. In Call of Duty 2, you can let that Nazi attempt crawl to some cover as you shoot around him for laughs. In Postal 2, you can light someone on fire and watch them as they crawl aimlessly on the ground.
By ESRB's logic, none of these games should've hit retail. This is confusing and totally not fair.
