I recommend watching the PAX East coverage, but be aware that it is 40 minutes long. It will show you more of the combat, features, and character customization. One of the best features of this game is the care that was applied to the story. It is a serious story, though I cannot say as to what the details of the plot are (good vs. evil or what not). It is certainly not goofy.
I was interested in this game well before I begun working there, though that may fall on deaf ears due to my apparent bias, haha.
