Game Rating Board
Year founded2006
For the rating template, see {{GRB}}.

The Game Rating Board (게임물등급위원회 Geimmul Deung-Geub-Wiwonhoe) (GRB) is the South Korean video game content rating board. A governmental organization, the GRB rates video games to inform customers of the nature of game contents.

Initially, the Korea Media Rating Board, a governmental organization, rated video games just like other entertainment media. However, a controversy occurred because the Korea Media Rating Board rated a gambling game called Sea Story as if it were suitable for everyone, allegedly due to a bribe. The Korean government got through the controversy by creating the GRB in 2006; it is now the only rating organization for video games.


Five ratings used by GRB:
