That's the thing, the game is a HORROR game, not an erotic game. Sex is incedental. You did not go there to get fucked by hot pornstars, you went there to find your friend.This game was pretty disappointing imo, you can't even pick a romance and the story is pretty much set to end badly.
(Yes I'm upset I couldn't get off with any of the murderers)
Which really makes me wonder "Why not both" but that was not the story they wanted to tell. As I said, major blue balls. Probably first time I was really tempted to write fanfiction.
