In a review for "GameStar", Christian Schmidt thought that the game's appearance and humor were poor, but recommended it because of its strong storyline. Todd found the pack's difficulty to be "wildly careening" and stated, "Some battles are amazingly easy. You can soar through many scraps in moments, with your party carving up the opposition before you can tell if you're fighting a mummy or a zombie. However, others are absolutely brutal ... There are more than a couple of moments in the game in which your party is ambushed by enemy spellcasters that rip you to pieces before you can even think about a proper response." He praised the game's music as blending in seamlessly with that of the original game, but criticized it for having a minimal amount of voice acting, with sequences of dialogue that begin with audio and transition into text. Steve Butts commented on this, saying, "the dialogue here really needs some work ... you'll even be treated to some truly tortured sentences. 'Wait till you see how deep into the backside of evil I insert my boot in the name of justice!' is probably my favorite. It's too bad there's not more voice acting in the game, because hearing someone speak lines like that out loud may have given the developers an opportunity to edit some of the worst offenders." As a result of "Mysteries of Westgate's" 2007 completion and 2009 release, it did not feature the improvements present in the two previous "Neverwinter Nights 2" expansion packs, and received criticism because of this. Todd stated that the game lacks the artistic improvements of "Mask of the Betrayer" and "Storm of Zehir", a sentiment echoed by Lafferty's review. However, Butts stated that ""Westgate" delivers enough engaging content that the absence of all the latest improvements isn't "too agonizing." Several reviews noted that the fifteen hours of story and the new objects in the adventure pack make the expansion worth its cost.
