@MormonWarrior: Yeah that was one of the big questions,who gets to decide what a "violent video game" is. And what will be alowd in video games.
Not sure what your questions are, but i think you mean if there are laws in place for movies? No there are no laws. They follow the same guidlines as games do. No laws in place so movie makers can still take risks and theaters are not afraid to show the R rated movies if a few under age kids get in cause they wont get fined out the ass.
