MapleStory's Chryse update adds a Greek-inspired floating island for players levels 55-75, and gives players the opportunity to battle Xerxes himself. And yes, you can dress up like a little Spartan warrior (pictured).

"After speaking with Chrysian chief Marione in the Greek inspired city, players can explore the once-beautiful island which unfortunately has become awash in darkness and danger. By re-establishing contact with the giants of Chryse, players will learn of the fearsome monster known as Xerxes, whose army of monsters has ravaged the local townspeople. It will be the player’s mission to battle Xerxes’ army of destruction and ultimately restore the giants’ power and peace throughout the island."
