This change apparently went into effect in 2020 but was noticed yesterday by AskAboutGames editor Andy Robinson while reviewing the rating for inkle’s latest interactive story game Overboard. Overboard is a reverse murder-mystery simulator where the player attempts to get away with murder on a cruise ship.
The game does feature mild violence, suggestively sexual themes, and depictions of alcohol use. But a scene where you can play Blackjack with another character caused the ratings board to apply a PEGI-18 rating to the game.
