IGN has an overview posted with plenty of exciting new details on character creation, events, weapons, and much more. The demo included quite a few events that the writer stumbled across and a battle with an "enormous, purple, glowing dragon," presumably an unrecognized Shatterer. If you've not seen the write-up yet, it's definitely worth your time.
While you're at it, pay a visit to the ArenaNet blog as well. The crew back in Seattle is keeping busy, and there is a new blog entry with a video entitled "Creating Guild Wars 2 cinematics."
Finally, don't forget to watch for Massively's recap of the Gamescom events on Monday!
