Blasphemers! I don't need the ass end of a weapon in my face to tell where I am firing. I also don't get the whole "we need iron sights to hit anything using a gamepad" argument. I'm not a Halo fan but I've seen people hit all kinds of stuff without the CoD crutch, and I've played Half-Life for a decade or so and never felt the need to introduce iron sights, when it was introduced in Battlegrounds 2 and Day of Defeat Source, it felt out of place for all but the most sniper campyish of aiming situations.
