The first person is significantly better in Standalone. The view doesn't shake, and bob as much as it did in Arma 2. I can't confirm Arma 3. That may be more improved than Standalone, but I wouldn't know. Also, it IS less realistic than Arma 2 as far as military combat simulation is concerned. However, DayZ isn't about military combat. DayZ is about regular civilians trying to survive. It is significantly more realistic in that regard.
