Huh, I was gonna get this if it had Korean songs.. So, like Hadrian said.. What's the point? People who can't speak Japanese get along with Oendan just fine, and Koreans are taught english in school so that should be enough for a game without many words.
Do you seriously not understand the concept of different releases for different regions? I know pirating all your games off the Internet can give you a skewed view of how things work sometime, but haven't you ever noticed before that there's different releases for Japan, North America and Europe (often even for individual countries in Europe)? So why shouldn't Korea be allowed to have releases as well?
Just think about it for a minute, it's really not too hard to understand.
man.. why does korea get stuff SO late
