Video game rifles

[S&Wshooter]

The trend in FPS' to put the ejection port of rifles on the left side of the rifle has got me thinking: Why the hell don't they just make the player character left handed so that the gun doesn't look stupid? You'd be able to see the shell casings comming out of the gun, but at the same time the designers wouldn't have to resort to incorrectly placing the ejection ports.
