In this thread we can find people who are into romance and a story-focused visual novel with broken characters they can sympathize with and immerse themselves in that world.
By definition an "adult entertainment" is something, e.g., movie, game, book, magazine etc., produced for and supposedly available only to people who have reached their majority, usually individuals 18 and over, which can be but need NOT necessarily be pornographic in any way, shape or form. (For example movies which contain scenes of horror or violence are usually rated as suitable only to be viewed by "adult" audiences even if they have no sexual content.) Fanboi seems not to have realized this and I get the impression that he abandoned Summer's Gone after seeing the "no sex scenes content" warning before the game begins properly and went no further: if he had actually continued, played and got into the game he might have found himself absorbed, engaged, affected and even moved by its genius and, despite his original misgivings, written a completely different review in respect to this masterpiece.
(Or not as the case may be.)
His loss, not mine, and he has my sympathy.
(Probably "got his hands full" by now with something else, from this very site, that caters to his peccadilloes better!)
