We may get more content with the princesses later, as I've heard that it's strongly hinted that we'll see them again in one of the two side games that are coming out between BS2 and BS3. However, said games, either one or both, may be focused on Red Hood as the protagonist, so it may or may not be the content we're hoping for. On another note, I've personally never enjoyed the rance series, as while I can enjoy rape being in a game on occasion, such as this one, I'm not a fan of it being so strongly romanticized, nor am I a fan of a game treating such an objectively, blatantly evil character as a hero. Not just the protagonist, but as a 'hero', something the games go out of their way to try to portray Rance as, as if the ends justify the means and that's what they actually believe, making every character that actually matters perfectly fine with him as a person, despite previous actions, even those done to them. I mean sure, game, you can feature an unrepentant, immoral rapist as your main character, but don't lie to me while you're doing it, and don't sugarcoat it to the point that it makes me want to vomit. Doing that just distracts from the experience and gives me really bad vibes, idk if that's just me or not.
To each their own, I guess, but I've just never been a fan of rape when it's portrayed in a comedic manner, especially when done so much in such an over the top way, as the rance series loves to constantly do. I'm also not a fan of such an overly cruel character being illogically depicted in a manner entirely unlike their actual character. It just creates a big disconnect for me, because it feels like the game is talking about a completely different character than the one I'm seeing on screen.
