No doubt - Arma series / Arma 3. The fact that you actually have a body and can rotate your head independently of the centered camera beats everything else. You also have many additional parameters that add to the experience - aiming deadzone, headbob, etc.
Awesome for a military simulator.
Agreed. Having glorious legs alone usually makes me very happy, but in ArmA, you even have a solid body! And a neck, as opposed to having your head welded to your arms. It's very useful, being able to aim and look in different directions.
And I really love how you can flatten grass by lying down on it. And do a little roll when you're prone. Sometimes, I just roll around in the grass in absolute bliss. Don't know why, I just love that feature.
