I totally didn't cry at the end of the game...Great story, this could totally work as a show or movie minus the sex stuff, well at least the "insest" stuff. I quotated incest because they aren't related by blood.
well technically it's still incest even if not related by blood, according to some laws... well also depends on the country. like if you're living in a country that has roots in christianity, then it is incest regardless of blood-relation or not, but if it's some other country, they only consider direct relations, like in japan or canada where they allow you to marry your cousin.
