As I keep going over the starting missions of the campaign to get the time bonus, I also keep trying to see if maybe I missed some important details written on the mission screens. But if I wanted to read rather than play, I'd get a good book instead of firing up a game, which brings me to my point.
TTS is already available for chat messages, but how about letting it read back the mission screens to those of us who are too lazy to do it ourselves? Just have an extra button on the UI to read it all aloud. Bad idea?
