As a GW 1 fan, my opinion may (alright, IS) biased, but I am really looking forward to this game. I am a casual gamer, who doesnt wish to put five hundred hours into a game just to be considered decent. I enjoy games to have fun, and GW allowed me to do that. I was actually starting to doubt GW2 was even being made until this trailer, due to the large lapse of time since their last serious update. Boy, I dont think I've ever been so happy to be proven wrong. I hope this game wil be just as good (or even better) than GW1 was to me. Only time will tell really, but I'm rooting for it.
Also, one of the first things I'm doing when Elemental comes out is mod a Charr race for my own personal use.
