discussing the similarities screenshots of their upcoming game have with The Legend of Zelda: Wind Waker
. The developer states that this is a coincidence resulting from the cell shades style of their game, and the particular hair and clothes show in published media. From the article: "a spokesperson from developer Webzen claims that the hero of the game does not have any fixed image, and is created by the player to be their avatar in the game world."
