( sorry my thoughts on this are spanning about 6 threads now)

Anyhow, yes, no voice acting would be a great improvement.

Ok other than suggesting you rerecord the entire death knights part my next suggestion is :

Remove the voice acting from all bit parts. Or at least almost all. Sort of like the first game.

Ok you have a voice recorded for the imp in the kitchen. All it says is " me clean this very soon"
Well, do you think it sounds professional quality? No? -Can- it, it does you no good.

Neverwinter nights does not have inclusive voices for all the characters I dont think its that important. It would be cool if they all were professional quality... but lets be frank here... the voices in the demo are from someone who never read a script in an acting class in their life. SOme of the parts sound good. Some dont... have QA pick through each character and just remove a lot of it.
