I have issues with iron sights. It's sort of a weird functional switch in your brain. When you're out of iron sights, that's when you're making your decisions and when you're in iron sights, all you're doing is aiming. So, one can watch footage of a CoD game while holding a stopwatch and you can precisely determine the percentage that the player's brain was turned on vs when it was turned off. in the case of CoD, it seems to be a very high proportion of mindlessness.

I get the gun porn appeal of iron sights, but I think they're such a product of realism that they don't apply to hypothetical future weapons. If you were designing weapons for a game from scratch, why would you even bother with cumbersome, old-fashioned stuff that has to completely obscure your target in order to work? Why wouldn't they have sights that allow you to SEE your target and give you a better periphery view? That's basically what Halo already has.

I'd be okay with sights as a part of the presentation value if it weren't an obligation to aim down sights. If it didn't grant any kind of artificial accuracy bonus.
