Yep, Korean. The stickers will stay in the box....I also have no idea what I would do with them!
Japan is tricky for me; I have no contacts there and Amazon can't export video games; its against the law there. I have been there but only found UT3 and UT2003.
The same in China, but I managed to get most of the games. Still need Chinese Unreal, RTNP and UT: GOTY.
