When I was new to this site. NTR really disgusted me and to some extension, whether I wanted to admit it or not the people who liked NTR.
It took me a year or two and I saw. They rarely got, what they wished for in most games. I started to feel for them. When I saw the words "it's not really NTR" the first time around it was almost like fighting words to me. Pissed me and many other people off, who were not into it and the threads often ended up being nuked. The truth is people looking for NTR just didn't get what they looked for in those games.
Like if someone tried to sell a game off as a hardcore sex adventure set in a fully fledged 3d world etc. etc. but it's just a strip blackjack game. Where you can only strip a woman to her underwear. I'd be pissed off too and say it's nothing like what it says on the tin. I'd be further frustrated if a ton of blackjack enthusiasts defended the hardcore tag, to warn others. Saying it was indeed rather lewd, to have the opponent strip in the game. They just wanted a blackjack game and the whole stripping thing is too much for them.
I sympathize and understand your frustation, though I don't like that genre myself.
Peace.
