I have always found that September is one of the months when everything is starting and energy is all around after the lazy summer. Never get that feeling any other time of year, not even New Year.
I even started my WoW account again. My old guild has moved from one name to another, but still all old people there and they still all remember me (even after I haven't played for almost year). Kinda enjoy it, but I still wait for Cataclysm as it will provide more new content. It is boring to know everything in WoW and there is not much left to do.
