This is a really great adventure game. It combines a series of four primary investigations (one introducing each "game board") and five fun little games to play against the people encountered in the investigation. I have been playing it obsessively all weekend, am not bored with it yet, and am sure there are more storylines to discover.
It is fun to choose from the different girls for your gang and to see their various retorts in some of the situations. Also to see how choices about which skills to develop for each girl make a difference in the game. And I have been particularly happy that investigative choices really do make a difference in the later development of the story.
I would enthusiastically recommend this game to adults or mature teens. Although by the "board game" nature of the visuals there is no graphic sex or violence, however, I would caution that there are some very adult subjects addressed by the story, especially toward the end. This is more true for some of the ways that the investigation can develop than for others, but all the plots I've been through so far imply the adult themes to some extent. Parents may wish to play the game themselves and discuss the issues raised with their children.
Very good gameplay: in many hours of play on a PowerBook G4, the only technical problem at all was a single instance of the correct word - actually, not a word but a double hyphen like those in this sentence, which may have been part of the issue - not appearing in a list that should have contained six choices but that contained only five plus a blank without either a word or a link.
Please note that I have not had the sound on so my "average" rating above simply means I have no idea whether the sound is good.
