The balance of paths is such an interesting conversation.
Usually the paths are defined by concept that the developer choose for those. In this case seems like a more grounded, long-term relationship by being a decent guy (Blue option) or by living the moment, being more bold and rash with words, leading to more casual and open relantionships (Red option). That's only my perception, and i may be wrong.
The problem usually happens when by trying to do something that is truly meaningful, the players are "punished" to have less spicy scenarios, wholesome scenes, or just the lewd progression is delayed for the sake of build-up in comparison of the other path, when you have the same talented writer doing the spicy thing that you wanted in other paths.
At the end of the game, is common if the game has for example 2 planned routes, if one is some kind of "romantic", "good-guy" or just even "respectful", that usually will have 25% (In most cases lest) of the lewd content just because in the same time-line, the action started way too late just because it needs build-up and then the game just ended because the other path just done everything
(And most cases, the game ends at the same point of the timeline, no matter which path).
At this point anyone might think that i want the opposite, but that's not it. I love the long term and interesting stories that unfold by a talented writer. I think myself a fan of stories that are driven by characters instead of scenarios, so that's why the maningful and deep relationship (Not always have to be romantic) attracts me the most and usually I end up realizing that it wasn't the focus at all.
One way to reward players that want that kind of content, is just by being loyal to the characters and let them grow with the story, a LI migh be shy and submissive if a path push her in a direction; in other path she can grow in a different way and lead to scenarios where she is more proactive because she is comfier and more confident. The limit is the talent of the writer, and by just doing that you can have the same amount of content, being as hot as the other path and even mantaining the traits of that characters that led you to that point.
I think this game does this very well, you can recognize a character no matter which path you choose, and have a huge divergence of how they interact with the MC (That's why i'm torn with this year and this game), but i, as well, recognize that if you played one side, will end with hotter / more scenes.
I'm glad to read that the dev is aware and open minded with the feedback, love the eventual streams and see that his direction align so much with my tastes. So hoping for the best and eager for the 2.0
