This topic is horrible, and you people have no clue what you're talking about.
Yes, we need ratings on our movies and other user presented content, but clearly you people don't know the first things about proper movie rating in the US.
Let me clarify it for you gentlemen*:
G - Guns.
PG - Plenty of guns.
PG-13 - At least 13 guns.
R - Real large amount of guns.
NC17 - Not counting 17 guns, there's still so many guns...
Guns of course is not to be taken literally. Shooting and violent killing is really the idea. In SMB, the fire flower for example is just as good as a gun. Or in Street Fighter, the people's arms are guns.
For those of you wondering what rating a movie gets which doesn't have a gun, it isn't even published in the first place, boring movies with no action are cause for rejection.
Now of course those of you who have a Kirby avatar might think it needs to be rejected and banned from the site because of a lack of guns. But don't worry, Kirby after he flies has air projectiles, he can shoot with various power-ups in many of his games - especially in the Super Smah Bros. series.
To show how I take this to heart and that even site administrators follow the proper minimum entertainment guidelines, you can see that
all the avatars I use contain the appropriate equivalent of a gun or other violent weaponry.
*I'd say ladies and gentlemen, but as is well known, all ladies on the internet are really gentlemen.
