8) Peripheral vision
Perhaps our soldier alter-egos are all tripping on acid - for some reason we’re almost always suffering from serious tunnel vision. Even a hallucinatory purple elephant would escape our detection if it were standing more than sixty degrees to the left or right of us, and as a result we all act like spooked race horses with blinders on, jumping around and spinning in circles at the first sound of footsteps.
The third-person perspective takes care of the problem to some extent, but, of course, removes the visceral first-person POV that gives games like CoD 4 much of their intensity. Widescreen TVs help a bit, but still don’t quite capture an actual human’s field of vision and spatial awareness. One solution is to extend the viewing area with a fisheye effect.
