I don't really go for the hardcore NTR style games. I also don't go terribly much for harem type games. Neither of them can really tell what I feel is an interesting story, or even one at all.
Hardcore NTR there's just one story to tell that I've seen. Full of humiliation and jealousy. I'm all for a story making me feel things, including negative emotions, but I don't want a constant downer beatdown. There have to be ups too.
And Harem games can't really tell a story. There are rarely any stakes, any conflict, or reason for me to pay attention because the only choices come down to "Do you wish to fuck this person? Yes/No". I started off playing a lot of them when I first found AVNs, but I got bored fairly quickly.
Sometimes I like things messy, full of drama. A rival competing for someones affection? Maybe a SO cheated on you? Maybe you're messing around with multiple girls and they find out? Someone trying to tempt you away from your current SO? Crush on someone who already has someone? All and more can be interesting. I'd like a game willing to go full soap opera.
And sometimes I like the romance games, meet some girls, choose to pursue one (Or more, but not without consequences) after getting to know them a bit. Changes depending on my mood. The point is I like a lot of variety, but mostly avoid the extremes in either direction.
