Gaming Nexus has tossed out the latest review of NWN 2: Mask of the Betrayer. Citing a tough learning curve, the editor assigned MotB an 8.0/10.00 score saying:

The polluted learning curve, however, has purchased a multitude of carbon offsets in the form of grand, high-fantasy storytelling; none of it watered down. No dialogue is wasted, and character development is meaningful and sensibly pieced together in tangible snippets. The soundtrack is as lush as ever, the cutscenes continue to be the antithesis of action-packed, but the scripting is massive and occasionally lights atop the Shakespearean (we're still talking contemporary video games, though, so don't overrate that statement).
