Yes, during this last year ntr skyrocketed and. Then, about 6 months ago, the same happened with drugs and specially with rape. It's not that they didn't exist before, but now there's a lot of demand for this games, apparently. I can find no other explanation to this fever.
the actual best explanation would be the fact that there's more people making porn games than ever before, as it's become a more realistic revenue stream for smaller companies and even individuals, compared to how it was, say, 10-20 years ago. as a result, there's
more games.
so, if 50% of all porn games feature rape/humiliation (not correct, but for simplicity in numbers here), and there were 100 porn games made per year ~10 years ago, that means there were only 50. but, now if there were 1000 porn games made per year in our current day and age, that's 500--the same overall percentage, but much more to go through
furthermore: sorry it's not your fetish but for some people (like me) it is. sometimes people find comfort in seeing a bad situation, maybe it makes them feel better about their currently not-so-great life--or maybe they just get off to sadistic/masochistic stuff for any other reason, and i think that's fine too
