This is the definitive incest game, if you're talking about mostly consensual B/S(brother and sister), and M/S(Mother and Son) incest. It's a bit old at this point, which means you're going to have to put up with some grainy models at times, there are no animations for the sex scenes, and the game is completely lacking in sound. However, the writing is so excellent that it mostly makes up for it. Definitely recommend this version to anyone who wants to experience the incest genre.
