Now what does the First Amendment have to do with all this? The First Amendment prohibits the government from abridging freedom of speech or the free exercise thereof. Where in all this would this be happening?

The proposed law would prevent minors from buying games with a certain rating. That's not censorship. Censorship would be if the game was banned outright so that nobody could buy it. And if parents can still buy the game for their kids if they think it's appropriate...then what exactly is the problem?

Quibble with the particular ratings all you want (I myself have issues with how the MPAA rates certain movies), but the First Amendment and the freedom of speech it protects has nothing to do with it.
