Help! Sights / Aiming First Person Shooters.

[averageguy]

Hi. I enjoyed for many years playing SP FPS games like Quake, UT, COD, MOH, Serious Sam, Far Cry, etc.. After an extended break, I'd like to play again.
I purchased MOH Airborne and Far Cry 2 to pick up exactly where I left off. Apparently, there's been a move toward having to hold down the R mouse button to look down the sights. This sucks for me. I either want a game where the point of view is naturally down the sights or I want to be able to toggle this feature. I want to be able to move as I look down the sights and I want some straight forward shooting fun.

Could you please recommend some games that I would find familiar. Thank you.

Well the obvious answer would be Far Cry 3
default it's also hold down to aim down sights, but it's easy to google how to make it a toggle.

Crysis 3 has it in the options. Bioshock Infinite is also toggle (very very awesome storytelling). I'll think of some more probably in a while

Thats gonna be a Problem! Because most games reduce walking speed and your FoV when you toggle iron sight. So it would be unplayable. Maybe with some moding you could change this, but then again (i.e in Bioshock Infinte) Weapons become way more accurate when you use iron sight (at least thats what i feel).
