I think clear cut choices are boring, that's why I like gamified NTR. It both gives me the choice to allow it to happen, and the choice to play against it. The HC series does have choices, but they only affect the ending:
And that's what I dislike the most in an NTR game, where the choices mean nothing until the end of the game. I as the player don't want to feel helpless, I want to be able to have an effect on the journey as well as the outcome. Though like I've said in another comment, I know full well that this isn't what these HC games are going for, which is why I only play them in short bursts. Hardcore corruption no matter what just isn't my thing. I'd prefer to have that kind of thing be a route I experience in a second playthrough. I guess my biggest gripe with the series is that the things that happen feel really preventable, but we as the POV just have to coast through it voicelessly despite very clear things that can be done to mitigate what's going on. I wish we had more agency, more to do, more of an effect on things - whether it be to increase the level or pace of corruption or to lessen it even a little bit, that way you can still have the corruption happening but maybe it's not quite so severe and the characters fight back a little harder, or depending on your actions they resist completely until the end. Anyways though, I do think the HC games are very high quality, and I do play them, albeit very slowly and I know that these games will probably never be my ideal idea of this type of game.
