Really? Because I know alot of games that don't have auto aim that have a FPS aspect to them. If it wasn't for the fact I have a 5600 dpi mouse, I would be able to aim faster and more accurately than my mouse.
Theres auto aim, its not huge to the point to where you notice your redicule following baddies but its there. Its usually for that small bit so your not over aiming or underaiming over and over again. MW2 and Halo 3 both had more auto aim then I would like to admit(as well as bullet magnitism "shudder") Its part of a simple reality in consoles while in PCs its not needed because of the superiority of the mouse. It may feel as fluent, but thats simply because they have a system they dont feel the need to tell you about doing a small percentage of the aiming for you. Even if there is an "auto aim on/off" feature if you hit off it just reduces it slightly. Look at RDR hardcoe mode, that aiming has very little auto aim to it so its easier to aim through the auto aim and over shoot your target.
