Square Enix and Sony Computer Entertainment Asia localized Final Fantasy XIII-2 for South Korea with Korean text and Japanese voice acting. The game came out on January 31 and was rated for ages 15 and up.
Next week, a new downloadable scenario starring Sazh will be released worldwide, but you have to be 18 or up to play it in Korea. Why? Because "Heads or Tails?" is set in the game’s casino Serendipity and has a new poker mini-game. Games with realistic gambling are pegged with an 18+ rating by Korea’s Game Rating Board. After reviewing "Heads or Tails?" and Serendipity Poker, the GRB gave it a separate adults only rating. [SOURCE]
