Why do these video-games have things like iron-sights? A lot of the games with that crappy aiming system are set in modern times. Have gun-makers never learned how to use bluetooth? All you have to do for a better aiming system, is attach a bluetooth aiming device to the gun, which transmits data into a pair of goggles. If you aim the gun to the left, the reticule in your goggles moves to the left. It doesn't take much battery power, and you could have a system where you can recharge the batteries manually. There are simple systems of electricity generation, where you turn a crank to generate electricity and recharge batteries. I've got that kind of thing on a flashlight, which means you could use the same system to recharge a gun/goggles battery.

Well anyway, I don't see how reality is an excuse to impose a crappy aiming system on video-games. If anything, reality should aspire to what video-games prove is preferable. If the best way to aim is by having the highest degree of visibility, then gun-makers should find ways of providing enhanced visibility. If not for the sake of guns, then for the sake of video-games.
