To satisfy my own curiousity I pose this question.
You're about to play this new game you bought. Having sat through the install and configured the grapic settings to your liking, you click 'New Game'. Upon starting the game, you're confonted with the first person view of someone pointing a pistol at your head; right between the eyes. You're sitting down. Thanks to depth of field blurring, you can't really tell who's holding the gun.
Now, what do you as the player, within the realms of this hypothetical situation, want to know?
