Game Service Restriction Alert

I'm trying to launch a game, but I get a "Game Service Restriction" alert.

[Country Restriction]

• This is an issue that occurs when you try to play a game only available in Korea with an account registered outside of Korea.

• Please try again with an account registered in Korea.

[Age Restriction]

• This is a problem that occurs if you are not of legal age.

• Please change to a server where you are of legal age, or try a different game.
