NWN2: Mask of the Betrayer - Review @IGN
IGN has posted their review of Obsidian's just released NWN2 expansion, Mask of the Betrayer, scoring it high with 8.5/10 :
Like in the original campaign, if you feel like taking a break from casting Meteor Swarm and swinging your + 5 mace, you can talk to party members, ask what their life was like before meeting you, earn loyalty bonuses for being sympathetic, and ultimately gain a better sense of the game world and why you're doing what you're doing. It turns out those you eventually meet up with have quite different, elaborate, and interesting takes on how events eventually need to be resolved, which adds depth to the narrative and colors your decision-making with twinges of emotional attachment.
You can expect the same kinds of dynamic dialogue options and outcomes here as with the original campaign, though these are ultimately more engrossing. If you prefer the brute force method you can mow down many of the game's obstacles, but there are some particularly intriguing dialogue options should you take a more diplomatic approach....
