For the life of me it's made no sense to have a separate rating system than what's used in the movie industry. There's absolutely no reason not to have the exact same rating system.
G - General Admission (E) pretty much puzzles and Winey the Pooh games
PG - Parental Guidance (E) you might have to hit something
PG+13 Parental Guidance for those under 13 (T) you might get a sword to hit something
R - Restricted for those under 17 (M) blood flows when you hit something
NC-17 - No admittance for those under 17 (AO) lots of stuff bounce
The movie rating system works and has been in place for decades.

Completely see what you're saying.. if its not broken why fix it? I see two potential problems/reasons why there is a different set of ratings. One is that the ESRB and the Industry wants to seperate themselves from the movie industry. It makes them look legitimate and that they can regulate themselves without help. You could ask the same question of TV ratings why not just use the movie ratings for them?
The other glaring problem is despite what Hideo Kojima wants you to believe, games and movies are two different mediums. Movies are also alot easier to rate. Depending on what you do in a game could potentially change its rating. If I type in a curse word for Link's name, I potentially just made an E+10 game into an M game. Let alone what happens if you go online and interact with other people on certain games.
The ESRB is really doing the best they can considering that this medium is literally in its infancy. It's not easy to foresee all of the possible challenges and difficulties the future may hold for the industry. It's a very challenging task and something that will eventually be figured out down the road but its going to take awhile.
