I've had SR2 for a while, I did like it, especially with the text-adventure sections, hah.
Hm, I do notice some in-combat chatter, and when Rada's health fell she did say something in German, just like that thread mentioned. I haven't had any "idle" chatter that I've noticed though. Such a shame nobody can tell us for certain precisely what speech we should hear so we can tell if it's working or not.
...such a shame it doesn't work perfectly too!
