It was user created content that caused all the controversy over GTA and Oblivion.

No. The "hot coffee" content was always in GTA, just not accessible. Can a Gameshark code be called "user-created content"?

Well, regardless, the point is that a proposal is on the table to make the ESRB play through "all" of the video games it rates. They could've played San Andreas for years, and they never would've found the "hot coffee" content, since it was not directly reachable from in the game. Or are you saying ESRB should be required to try every possible Gameshark code before it rates games?

For the purposes of this discussion, there's no difference between truly "user created content" and "enabling unreachable content by minor modification of the running executable." Neither of them is something the ESRB is going to be able to pass an opinion on until the modification happens. Since this legislation in supposedly in response to the recent "scandals" of GTA and Oblivion, it's worth noting that it would've prevented neither.
