Also, they have microtransactions.

Like many of the imported Asian MMOGs, Zu Online has one aspect that sets it apart from the Western MMOGs: a diverse selection of armors, clothes, and outfits to place upon your character. To show you just how diverse some of these clothing sets are, the developers at Zu Online have distributed some pieces of concept artwork for potential players to view. The staff at Ten Ton Hammer collected four of these pieces and have displayed them for you to enjoy!
