And even more insites from a Black Isle Staff member:
"There is also another form of interaction that was
surprising to me.
The amount of discussion you can have with fellow party
members, while they're IN your Party! You can talk to Annah
about her friends, her past, her skills. You can talk to
Fall-From-Grace about how she Feels about other party members,
including you, how she thinks they feel about her, how you
feel about her, etc.!
You can have members teach you skills! Talk about they're
own special talents! Even gain experience from this knowledge!
And this information changes throughout the game! These
people really feel alive!
To add one more level to that, people that you meet will
acknowledge different party members, sometimes ignoring
you in favor of them. Talk to a githzerai townsperson. Doesn't
say much. Now, talk to him/her with Dak'kon in your party.
If you can get a word in between them, you might get some
The amount of sound in the game is righteous too. There
seems to be layer upon layer of ambient sounds. For example,
in a place called the Smoldering Corpse Bar, You hear tons
of voices coming from all over the bar. As you pan the screen
around, (or move towards areas of the bar) you can hear
more sinister voices near a table full of fiends, laughter,
and discussion over by the warriors, and the sound of flames
near the big furnace in the front! That's one area!"
