I imagine that this would be pretty difficult. If they worked with a game designer (Like EA) they could use their engine, making it easier. Although that would likely run a pretty penny, and the amount of data would be HUGE.
If you're looking for something more interactive, it would be way easier to just have audio. Like you're listening to the radio. Yes, some of the phrases would be used all of the time, but I think it's something that would be more manageable.
