"I thought you were arguing that a side view of a rifle that does not include aiming down the iron sights"
Oh it can include aiming down the sights, with the other eye.
Well it's a matter of which is more realistic, is it realistic to lose the vision of the entire left field? I don't think so, it's treating every player like a cyclops.
I don't mean "realistic" as in pixel-perfect recreation, I mean it isn't unrealistic in the sense of "Games without ADS are SOOOOO unrealistic, no way you can hit anything with that accuracy without using the sights". Realism not in the sense of superficiality but the practicality of "you can't be accurate with a gun without visually lining up sights)
Well considering parallax perspective and both-eyes-open shooting they may very well be aiming using the sights.
"Both of those shooters are aiming with the sights."
This is what you don't address, how can you REPRESENT the increased vision you'd have with both-eyes-open that has accuracy of lining up sights with the target and also not having a quarter of their vision obscured by the weapon body as you see here:
See the part of the screen behind the gun, that would be concealed from right eye view and is obscuring targets you are trying to track, that would be visible with left-eye view.
I think a lot can be said for the classic view is all, in that - in some ways, such as fields of view - the non-ads type games are more realistic. Considering how many shooters are trained to shoot with both eyes open it would be unrealistically forcing all players to aim with greatly restricted perspective with the COD style ADS.
