If there were ever two things made for each other, that would be real-time strategy game and South Korea. They love each other so much it hurts.
The game is hugely popular in South Korea — and has been for some time. Korean Air is sponsoring the OnGameNet StarCraft League this spring, and this ad refers to that league. The ads range from the humorous (above) to a documentary-style look at professional gamers like NaDa (aka Lee Yun-Yeol) as they travel and play.
These ads also serve as a good primer for StarCraft II, which is expected to be released this year. Release date is TBA.
