Re: We need those icons!
The ESRB gives the following advisories for GTA4 (rated M): Partial Nudity, Strong Language, Strong Sexual Content, Use of Drugs and Alcohol, Blood, and Intense Violence.
Correct me if I miss the marks, but the likely scenario for GTA4 east of the Atlantic would be an 18 rating with the following icons:
-a black bar across the top half of a female caricature
-a cartoon balloon filled with symbols commonly seen at the top of a keyboard
-the hypo (as mentioned in the article)
-a bottle of liquor
-a caricature of a limb with a drop coming out of it
-a knife (to signal that the violence is more intense than that shown by the fist icon).
The only one I can't put a discrete icon to is the one for strong sexual content. That one's hard to describe in anything other than words without going over the line.
