I'm not overly crazy about the DK voice, but it is the orginal one that was used and before the end of act one I'll bet that it will make no difference at all.
I still stand bt this. If the Larians do shange the voice ok, if they don't ok. The voice is not the only thing that I look at when thinking about buying a game. I look at the whole game and If there is one reason that is small as a voice that I don't like about a game, guess what, I'm buying that game.
