Boosts performance of the game by ironing out a few bugs with the graphics helping it look better and run smoother, also fixing many NWN2 game and tool set bugs. Some thing I found as a blessing as I don't always have the luxury of the net to get the updates.
Adds more depth to the single player experience and a solid storyline that offers difficult but rewarding challenges, actually reminded me slightly of the baldurs gate series which is never a bad thing.
If your a fan of the series its value for money because if the next expansion offers what this one has brought then it'll be a step in the right direction to the what NWN2 was supposed to be.
Four stars for the enjoyment alone...
