I could have sworn this game was an MA-17 at one point (I watched a few clips of it and it has things like things crawling out of a woman's cleavage in a painting.) But now I can only find boxes marked "T" for Teen.
This ad with all the snot has the box showing an MA-17. Guess that must have been before it was finished.
This is a very forgotten game, AVGN covering it would probably not be out of line.
