This is actually pretty old news... it has been known that Kojima\'s team of guys have been working on something like this since the before even the first trailor of the game was shown at E32000.
I personally think that it\'ll be a waste of time to write such a program. Just because it\'ll most likely be a series of questions that they ask before the game even starts, in fact that is how it was previously stated by Kojima oh so long ago as to how it would work. And if it\'s a series of questions that try to determine your age, or level of maturity then that\'ll be easily cracked by just repeated tries in answering the questions or some place on the internet explaining how to do it.
As for it determining your age through the way you play... I don\'t think this will work either. Just because there are so many different styles of playing that people have. The possibilities are almost limitless. Of course it could go for things people do in a similiar manner then I could see how a program like that could half way work, but still not completely. I mean, there\'s going to be a lot of 25 yr old guys out there pissed off at Konami because the game thought they played like 15 year olds and toned down the blood. Do you kind of get what I am saying?
Well, I am kind of anxious to see how this program really will work, and how effective and accurate it will be, but for now I am still betting that this program will be a waste of time in the development area of the game. I think it\'d be better if they just had an adult lock-out password, similiar to what they had in DukeNukem3d. Just better encrypted of course

I think the idea itself is good though......
