I could see chatter in a mission, but it would be much like it is right now where your wingmen will tell you if you're being targetted, like "Watch your back pilot!" Now in the current game, all of these only apply to the player, and not to any other fighters. The chatter I could see between the other pilots would be more like "Alpha 4, you've got one on your tail!", or "Nice shot Gamma 2". Unfortunately, we don't have the audio to generate such messages, and using existing ones would be confusing to the player. I can see only 2 possible ways to get this coded in the game, and I don't think you'll like either of them. Number one, propose it to Kazan for Ferrium, which would take some time to become reality. Number two, (no flame please) propose it to Derek Smart (or more importantly, who ever he hires to create the engine) if he manages to aquire the rights and creates the dreaded FS3. Of course, neither of those 2 options have any guarentee of success.
One more thing, I know I mentioned mr. Smart here, but I don't want to derail this topic, so please try to save further replies regarding him to more appropriate threads. Thanks.
Later!
