some people love others don't care others don't favor them. Me i personally think if done correctly will make it realistic. If you ever fired a gun ( i have and know what i am talking about) than you know that you don't fire from the hip. Except shot gun. but u don't pistol, rift. NO. People in the real world always look down the sights. Not from hip. You even see it in movies.
So. My idea (which i know not all will agree) is that keep iron sights but when not aiming keep the gun down what i mean is lowered. You are still holding the gun. Aim or iron sights you would move gun up to fire. Prob be better with more body awareness. And if you want to fire while not aim it than the gun would go up like iron sights when not firing for few seconds than back down. So for games that feature talking to people it wont be weird that your holding a gun up to there face.
Would be cool for some games maybe prey 2 that you can draw your gun and put it back into your holster. Thats just me
This is a few of the things i think about the iron sights mechanic.
You be surprised at what you can think up when your board flying in a plane or in the passenger sit of a car on a long road trip.
