GRB: ALL

From Wikipedia

The Game Rating Board (GRB) is the South Korean video game content rating board. A governmental organization, the GRB rates video and computer games to inform customers of the nature of game contents.

Initially, the Korea Media Rating Board, a governmental organization, rated video and computer 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.

All: Games that everyone can play.
