CoC is one of the most important games to come out in the true indie space. Outside of the great erotic content, it does manage to have a lot of interesting life sim elements and so many little hidden things. Although this stuff is part and parcel of the japanese eroge scene for decades, the fact that Fenoxo and crew had almost an convergent evolution is only a good thing and brought a very smart queer element to the sex game genre.

Seriously though, its great.
