G is Zora the the Last Bird. PG is Brian Home Alone. PG-13 is The Not-So Little Einsteins Movie R is One Graduation and Lots of Funerals. NC-17 is Sex, States and Violence.
GP is for Parental Guidance. They changed it to PG, because it was too Weird, I thought it Said Guidance Parental, not Parental Guidance. M is for Mature Audiences. This was replaced to PG-13, cause it's stolen from the Game "M" for Mature. X is an Unofficial rating for Adults, it was replaced to NC-17, because X is for Adults Only.
