The editors over at IGN have cranked out their own review of Neverwinter Nights 2: Mysteries of Westgate, giving the adventure pack a score of 7.0/10.
Despite a few key problems, the Mysteries of Westgate was an enjoyable experience overall. Yes, the mask is inconsequential except as a topic of conversation and the story sometimes seems to lose its focus, but the quests are enjoyable and the opportunity for real roleplaying abounds. At ten bucks it's priced to move for ardent fans of the Neverwinter Nights series. Those players who never went beyond the original NWN2 would be better served picking up either of the two previous expansions instead.
