The Aurora World just that awesome? You decide!
What we can tell you for certain is that the Asian fantasy import is in closed beta as of right now. You can get a free key at the game's official website, where you'll also learn more about the 300-player Nation Wars system, the hybrid pet/mount mechanics, and something called a "coliseum mode."
You might also want to have a look at one of the game's trailers after the cut.
