Every new release is new writing, choices, renders and animations, so that's a BS reason. Nothing is stopping BD from doing it except that he presumably doesn't want to. And perhaps that some people wouldn't be happy if we had for example Jamie going and lezzing out with Zoe or whatever, though he has said before he DGAF what people think of his game.
Yes, but just adding one additional protagonist can mean as much as
double the work (in terms of writing, choices, renders, and animations), and will essentially be twice as much effort, so it's far from a BS reason. Sure, maybe BD can reuse a few renders and common dialogue here and there, but it's going to be a lot more effort than "just" new writing. Keep in mind, the renders in the current game are from the MC's POV, so new protagonists need to account for this in special renders.
It might be an unpopular opinion with the moderators here (MODS: I apologize for this in advance), but if you're that unhappy with the choices available in this game/VN, no-one is forcing you to play it, the same way that nobody's forcing you to read a book where the author has chosen a path that you don't agree with. And BD, as well as any other VN/game author/developer, are not required to give a f--- about what people think of their games. Stories are often written with an outline beforehand, and writers sometimes stick with their intended story regardless of others' opinions, or they may take outside opinions into account. That's entirely up to the creators themselves.
If you dislike the choices available that much, and you don't think you're being heard, stop playing the game, show your dissatisfaction by giving the game a low rating, and move on. And if you're also a paying subscriber (through Patreon/SS), show your dissatisfaction by pausing or ending your membership.
Personally, I like this game and its story, and even though I don't 100% agree with the choices available, I accept them as part of the story. Or, in some cases, I accept them as part of
the way I opted to play the story (in terms of the walkthrough's Cheat/Loyal path). In fact, WVM and its creator is at the top of my list of creators I plan to support as soon as my economic situation allows for it.
