Skydiving
In my experience not many games have skydiving but some do like Legend of Zelda Skyward Sword for the Wii (picture to right).
Just as with swimming we can
look to Newton's laws
to explain the physics behind it. (picture taken by me)
Let's draw a Free Body Diagram of what is happening in our picture. We have 2 forces acting on our object, Air Resistance (Drag) and Gravity.
When the object is first
falling gravity is greater than drag but when the object hits
terminal velocity (maximum falling speed) our diagram changes. 
Drag and Gravity
equal each other in magnitude at terminal velocity, which means
the net forces are zero and the object is now falling at a
constant speed.

Sum up of Skydiving
What you should take away from all this, is that 2 forces are acting on your falling object. You have to take into account your object is accelerating down until it reaches terminal velocity which is a constant speed where Drag=Gravity.
