DA is sort of like playing an interactive movie. I'm a sucker for cutscenes. They really add depth to the NPCs...since they interact with your character so much you really feel like you're a part of the story.
I'm so looking forward to it. Pre-ordered ages ago. I enjoyed the first one so much, so I have high expectations for this installment. 2/22/11 they will release a demo, so at least it will give us a taste lol.
