The original game suffered a bit due to some frustrating bugs upon release. How much effort is being put into making the expansion as bug free as possible?

We achieved our first play through of the entire game back in early June, which means that since then we've just been polishing. We've had the time to fix a lot of minor bugs from Neverwinter Nights 2. We're not really touching the original campaign (from NWN2), but we have solved many game play issues. Also, we've spent a lot of time since NWN2 launched in optimizing the game so performance has improved.

What new feature above all do you believe that fans of the series will love the most?

Without a doubt, Mask of the Betrayer has the strongest storyline and characters yet in a Neverwinter Nights game. That's not to say previous NWN stories and characters haven't been great, just that I feel we've really outdone ourselves this time. (And it's not my story or characters - the credit goes to our creative lead, George Ziets, our module designers Jeff Husges, Eric Fenstermaker, and Tony Evans, and our companion writers Matt MacLean and Chris Avellone.)

Thank you for your time, Kevin.

My pleasure!
