What then is the purpose of a pixel perfect iron sight that does not shoot straight (and how does that appease or benefit the straight FPS player that hates to miss "when they obviously didn't!"). ?
"immershun"? basic firearm discipline? alternatively, common sense - even somebody who has never held a gun in their lives, never SEEN a gun, will probably know that even if they have no idea how to hold a gun they'd probably hit their potential target a lot better while using the little pointy thing on top of the gun (the "iron sight", as it were) as a crosshair than they would if they were just sticking the gun in that general direction and pulling the trigger.
ed actually i really like the idea of INT 1 meaning you hold pistols sideways and everything else is raised but to the side like it is in Fallout 3
