The game's been in development for like 3.8 years. While I understand that's a long time to stay interested in anything, the thing has 495,000+ words and 11,800+ images. A Dance with Dragons has 415,000 words, and took almost 6 years to finish. And that doesn't have pictures, coding, or multiple-choice story branches to worry about. And George RR Martin doesn't have an actual day job, or update a blog a few times a week, or field questions from Discord and this forum, and and and..
Also, you say that only Nicki, Ashe, and Mason have gotten much development. But Risa has had multi-option ero scenes and her whole story's been laid out. Brittani's had a whole chapter that basically belonged to her, again with multiple ero scenes. Pepper had a whole mini-game dedicated to her. Ditto Alex. Viola's had quite a bit of content to set up her next arc.
I mean, at this point you've at least had the opportunity to see every love interest naked, save Carolina. And Carolina and Alex are the only two people whose plotlines haven't really gotten going yet. Everyone else has basically had their thing introduced that Guy can either assist with or exploit. Nicki's plotline has basically wrapped up. Ditto Mason's. Risa's can be done, if you choose that route. Gabby's macro plot is basically done, but smaller stuff like family and relationship dynamics remain. Brittani and Ashe's plotlines are pretty closely linked, and in the next two updates we'll see how those develop.
I've said this before, but introducing characters is tough. Getting them to their first sex scene is tough. After that? Much easier. The first chapter of S2 covers a lot of ground, and basically every love interest is touched on. After this one is done, I'll be doing shorter chapters for at least the next year, because these giant ones are kinda killing me.
