No. And it's not koreean. The company is from the states. And it used to be called "poor's man UO". For some reason. And the screen-shot is from the "3D" version of the game, it used to have an even older version, a bit better than a MUD . Like Ultima. I don't know what more hints besides the name I could provide.
P.S.
@Crassus I used to play it on a dial-up connection. So yeah, it's pretty old. Start of this century old but looks like 1997
