What's the main reason to be excited about NWN2?

FB: In a nutshell, it's everything about the first game - but more so in almost every direction. One of the major things we've focused on (having started with the Aurora toolset and the Aurora engine), is that we have this whole new graphics engine which we call Electron - it's fantastic and truly next-generation. We've also been able to start on the story from absolutely the first day, which has meant we've really been able to deliver a top-notch single-player experience, as well as a fantastic toolset and multiplayer experience.
