In fact, most rape games fail for two reasons: Because their plot is too bad, and because there are no real choices. You can only be evil, or be evil. That doesn't happen in Fin. You can be mean to some girls, nice to others, or even change your attitude. For example, in my main gameplay, I started out being mean to Nicki. But then I started to like the character, and I didn't want to treat her badly. So I changed my attitude towards it, and I loved that because it's a small redemption arc that I had never seen in a game of this type (and not because the game forced me to do so, but because I chose it based on how I felt about Nicki's character).
On the other hand, one thing I would like to clarify is what we are talking about when we talk about Dark Path. Do we mean rape anything with two legs? Because for me blackmail, or financial submission is also a pretty dark path. Yeah, you're not throwing the girl on the ground between garbage cans to rape her like an animal. But either you're forcing her to do things she doesn't want, or you're taking advantage of the fact that she needs the money.
I agree with
NeonGhosts that the violent rape scenes have a short history. But one thing that I loved about the last update is how Ashe's arc was treated. In my main gameplay I raped her next to some garbage cans. But in the last update you have the possibility to blackmail her, and force her to have a date with you. That path has a long way to go, because it's not that you rape her again in a dark alley, which would have been "meh", but that you force her to submit to your desires by other means. Is that a dark path? A lot in my opinion, but at the same time it is interesting. In fact, the character began to interest me in the last update as a result of the scene of her in her room, where she really looks desperate. She doesn't want to date you. She doesn't want to see you anymore. But she has no choice but to give up, dress pretty, and go out holding the arm of the guy who raped her behind some garbage containers. That's more humiliating than any S&M shit.
