Common Sense Media is a site which has extensively catalogued content in film, gaming, and various other forms of media to help parents figure out wether little Timmy really isn't old enough to play his first T rated game. Now I don't have to explain the ESRB labels out my ass, and I have reason enough to execute on sight any parent who doesn't allow a child to play an M rated game until the very moment he/she turns 18 (becuase the law says you have to be 18 and I'm always right, they say when I point out the nice 17+ part of the rating label). A few of my cousins are gamers, and when their parents come to me for suggestions, the Mature rating deters 90% of my suggestions for a 16-year-old, just like T turns away parents of 12-year-olds.
I pray that this will lead parents of younger children to an even better practice; researching these things so aunts and uncles don't throw a 5 dollar Wii game under the tree when they own a PS3. Also, maybe this will be the last bit of push parents need to keep the 10-year-old population of Xbox Live in Rock Band and out of Modern Warfare 2. I CAN DREAM DAMMIT!!
Seriously though, MS needs to add Puberty to the next mandatory update...
