Koreans are people who live in or come from Korea (usually South Korea a.k.a. Republic of Korea, because most North Koreans are not allowed to travel abroad). But here we will deal with the ones in the United States of America, including those whose family currently lives in Korea.
There are all kinds of Koreans, but to name a few:

American-Koreans (so-called twinkies/bananas)
people who have spent their entire lives in America. Usually US born and second- or third-generation immigrants. They either can't speak Korean at all or understand very little of it; but they do have impeccable English speaking skills and lots of white friends. Most feel uncomfortable around other types of Koreans and/or some older relatives. Very Americanized, with no understanding of Korean tranditions or Korean pop culture. Less intense when it comes to school and work; only few of them tend to show outstanding academic performance. They all have English first names.

Korean-Americans
include Koreans who came to America as kids or those who have spent many years at American schools. Many have English first names but some choose to keep their Korean names. Good English, but their English speaking abilities depend on the number of years spent in America or the number of American friends they have. Most are academically successful and get straight A's. There is 90% chance that a given Korean-American plays a musical instrument and/or excels in math or science. Some can be good atheletes. ...

The people who you don't want to play at Starcraft. Their culture is basically Starcraft and they worship the Overmind. Like how people evolved from monkeys into civilized people, Koreans evolved from monkeys to Hydralisks and Zealots.
