Hey. So you know about the whole iterative development process thing that we do here at ArenaNet? We have talked about walking in the past and said it wouldn't make it into the game. However, things can change in the world of game development. I just talked to Eric to double check. He confirmed to me that your characters will be able to walk in Guild Wars 2.
