A real joke
Any lawsuits against TT/RSG should have been dropped and the parents of any "children" playing GTA should have been thrown in jail instead.
The game was rated M for Mature.
To quote the ESRB from their site:
Titles rated M (Mature) have content that may be suitable for persons ages 17 and older. Titles in this category may contain intense violence, blood and gore, sexual content and/or strong language."
M may have Sexual Content people...
The stickers on the game also often say "strong sexual content, partial nudity".
I have GTA4 on my XBox360 which is also rated M 17+, and when audio is on you can hear the number of children playing the game is very high. Almost every game I connect to there is at least one kid somewhere between 10 and 13 playing it, which is easy to tell since his testicles haven't dropped yet... err... his voice hasn't changed yet.
I guess that parents shouldn't be bothered with actually looking after little Johnnie though, that's what lawsuits are for.
TT should be able to counter-sue any parent who purchases the game for their kids that are underage.
