A great treat for the NWN community - after so many years, a new official premium module.
I played the DLC over the weekend, I believe the predicted gameplay length of 10-15h is about right. The story is good. While it's not on par with NWN2's Mask of the Betrayer (which to me is the best story told in an RPG), but I enjoyed it quite a lot. The final part of the adventure was amazing, I could really feel the epicness. A warning - there are a lot of tie-ins to previous stories and you should play this only after all of the official campaigns, as well as after Darkness over Daggerford and Tyrants of the Moonsea. Not because it's required to understand what's going on, but to avoid spoilers from those earlier adventures. For someone who played them, however, the tie-ins are a great treat.
The recruitable companions could be a bit more fleshed out, I feel. Whereas in Tyrants of the Moonsea companions played a larger role in the plot, here they're for the most part just tagging along instead of being vital characters in the story. Their AI could also be better and henchman dialogue could include more options, like making a bard companion cast Bard Song.
New content is great: very cool new monsters (looking forward to seeing them more in future custom content) and new music tracks. They managed to create a great atmosphere of traversing the cold and harsh lands of Icewind Dale.
I was a bit worried that the story will be left unfinished given this is the first chapter of a longer campaign planned, but while there are plots left hanging, the module's main story is neatly tied up and I do have a feeling of completeness (which I can't say about another old premium module that was supposed to be continued, Witch's Wake).
As for bugs, I've encountered only a few, none of them game-breaking.
To sum up: great stuff for Neverwinter Nights fans. I'm looking forward to the rest of the Blades of the Netheril campaign!
