Below are five films, one of each BBFC certificate: U, PG, 12A, 15 and 18. All that the player has to do is match which one's which.
I gave this game a test run on two people, both of who were equally unenthused. Sigh. Still, should I ever meet someone IRL who's as obsessed with film classifications as I am, I can share this game (and Levels 2 and 3, to be posted!) with them!
