You named 1 game which isn't even classic NTR that we are talking about, it's adventure series about Rance going around and f*ing fantasy world women. Did you even play Rance? You call that NTR????It's not NTR focused but it definitely has NTR moments/elements; The Rance series' lead writer & original creator was a woman, at least up until near the end of the franchise. Pretty sure that's more than 3 games, easy. What now?
I explicitly said that adventure/dating sim with NTR element is not what I am talking about, there are thousands of games like that. Rance is as much NTR as SummertimeSaga is
