There are more people in this community that will agree more with you then TysonL. NTR/sharing community is a minority compared to every other fetish. You cater to them you push everyone else away. If a game has NTR etc... I and probably many others turn on the skip and fast forward just to check out the scenes instead of getting invested in the story and characters. I could totally get into another Summer's Gone styled game with no sex scenes in it.
Let's be honest, over the past few years, most members of the AVN gaming community have not cared about the story. They only watch the H scenes and rate the game based on their fetishes, rather than the quality of the game itself. Comments like "Add NN content or I won't play your game," or "Remove NN content or I'll give you one star," have become the norm in the AVN community. I'm creating a game for me, so I don't want to focus on stuff I don't enjoy.
