Larian, please,
PLEASE don't make the voice acting repetitive.
It was "cute" in OS1 and became a popular joke, but it's SUPER annoying when an NPC repetitively yells about cheeses every 2 seconds. I would lose my mind and completely mute the game when I took longer than a minute browsing the merchants' wares.
So please, either
give the NPCs more lines, or
make them say their lines less frequently... Or perhaps
add proximity to sounds so when they're far away, they're not as loud.
or.. well.. preferably,
all of the suggestions above.
or at very last they could mute the voice over when you have your inventory open.
