I really enjoyed the game. It was not at all what I expected, and the people giving it negative reviews probably have not actually played the game. Yes, it touches on the fact that an older man had an affair with a teenager, however, there's not much in the game beyond that fact. It does not touch on any sordid details like many people were implying.
There is nothing graphic, nothing that alludes to sex, or even that romance between the two. In fact, very little touches on the personalities of Rachel and, Nicole's father, Leonard.
This was basically just a mystery type game set in a very spooky and eerie. environment.
