Korean is a really hard language to learn actually. The vocabulary is really complex. But I have a Korean mom so she yells at me all the time in Korean, thinking that I don't know what she is saying. She cusses at me all the time. She doesn't know that I know the actual language because I never talk to her in Korean, but I have done research and I have listened to her when she was a conversation in Korean with someone.
When I went to Korea last summer, all I did there was play Soldier Front. They have like tournaments on the news and stuff. They have game tutorials on stations on the TV. It's extremely popular.
