I have a preference for themes that involves corruption of naive women, so NTR and Netori games are, in general, a full plate, because the bad guys have the worst intentions and are smarter than the protagonist. It's good to see when the game author creates situations involving a woman and a bad guy, that results in a unexpected event (of corruption, of course). But it's very hard to find this situation on western visual novels.
I don't put myself in place of the MC, personally, most of the time I dislike the MC. Also, I don't like any of this kind of thing in my relationship. Like someone said here in a previous post, I have also a relationship in real life and I play these games just for entertainment. Real life is so different...
