If you enjoy anime and/or anime styled games, this is a fun little game to try out. Can get a key from http://www.mmorpg.com/giveaways.cfm/offer/488/Auro-Kingdom-Closed-Beta-Keys.html there are still about 1,000 left of this post. Aeria Games runs it and they have given out several thousands of keys already via various means, so the game is pretty populated around the clock.
(I'm not sure if there is a NDA or not, Aeria does their Betas differently from other publishers, but just in case, I'm afraid I can't answer questions or give more information.)
