"Hidden" Stats (from american.gxt)
The following stats I found were in the american.gxt file. I found these when people were asking if my PHP Stats was a complete, comprehensive list. Of course I wanted to be sure, so i checked through the gxt file and I managed to find all these which for some reason we aren't shown (some of them are from features taken out, such as Drugs and Rampages).
These are the stats we never get to see.

Judge for yourself what you think of all these stats, maybe features like Drugs can be made available through hacking the .scm file. the Hot Coffee mod is a good example of this, you could probably have also achieved the "sex rating" stat had this feature been left in the game.
