When I gave Dave the pit to test for the first time, I pre-loaded all the MFD buttons and rotary controls in the cockpit with farm animal noises. I wish I could have seen the look on his face.
They have since replaced them with suitable clicky noises.
I tried to convince my wife that the world might be a better place if all weapons emitted comical noises when used.
Do keep in mind we don't quite have the same resources, budget or team expanse as Battlefield Bad Company 2 or other AAA game. If we did we'd have a fully streamed world, sound cones and motion capture. But as we didn't have $50,000 to spare but only a tenth of that farmyard animals it'll have to be. (That last bit was a joke).
We will do what we can. As Flyboy says, I'm all too aware how far it goes to create a sense of space. (I'm not promising anything, I've been working on a viable method to have sound travel at realistic speeds, we'll see how it goes, there are issues with camera switching. But it might be confusing to blow a vehicle 1km away and not hear the bang until 2.5 to 2.9 seconds later).
