Realism is what we are looking for. Not realism that breaks your ability to enjoy the game but realism that bring the WOW into visual fidelity. The idea I am putting forth is to make people skeptical of ArmA 3's beauty see just what it is capable of. ArmA II already had on some maps wind sounds. Let's make ArmA III the next most realistic simulation by making the environment act like a real environment. When it rains and the wind blows, a player should be able to forget they are inside and "feel" like they are in a thunderstorm.
I have found a few examples of what I have been referring to.
Here is an example of the waves during a storm or heavy winds.
Here is rain hitting a metal roof.
Here is heavy rain effects in a vehicle
Here you can see the sheets of rain gusting about.
