To be fair Larian doesn't have the same budget of Triple A software houses like Bethesda, their best selling games sells for hundreds of thousands while games like Fallout or Skyrim sells for tens of millions, even if the percentage for the italians sales are similar ( around 1,65/2% both for Original Sin and Skyrim) you have to take into account that the 2% of something like 20.000.000 (a game like Skyrim wich is among the first ten best selling video games of all times) isn't exactly the same as the 2% of 500.000 (this is the number of copies they needed to sell in order to get even with the development costs, as stated in Swen blog after the release of the game. The actual sales numbers should be higher).
The voice over is a total different matter, while I would have preferred more localizations instead of the voice acting I can't really blame Larian studios for choosing it since it makes the game much more appealing toward the vast majority of players (around 60% if we only take into account the sales for the native eenglish speaking countries)
