Another interesting Korean rating:
Castlevania Requiem: Symphony of the Night & Rondo of Blood for PS4 has been rated by the Game Rating and Administration Committee of Korea.
There is no more info, but it seems that Castlevania Requiem could, indeed, be a collection including Castlevania: Symphony of the Night (1997) and Castlevania: Rondo of Blood (1993).
Stay tuned, TGS will open its doors in a few hours.
