Darkexecutor has spoken about the fact that having to pay an artist for so many animations, possibly combined with the small number of sales, made the game economically unviable. The 3d models were a method for him to be able to cut costs. I'm not saying it's good, but our friend has to eat somehow. Though I'm aware that probably just raises further questions.
Incidentally, Darkexecutor, did you want to be a game developer full time? Are you, at this point?
I'm fulltime dev, but that's only because I live in a poor country, otherwise I wouldn't be able to keep this. I had to take side projects to survive though, anyway. As for the art style - I saw the complaints on Steam, I read the reviews, despite I don't control that account. My short answer is: when any NSFW Patreon game loses original 2D artist, there are three options - 1) Abandon the project and start a new one, because finding artist to keep everything within the same style is very difficult even when you have budget, and when you don't have it - it will not work; 2) Invite other artist and hope that people will not notice several different art styles in the final game. Some famous Steam games did it, I don't like this way; 3) Scrap existing art and try to mimic existing art to some point where you can finish the game to some point.
I chose option 3, because I care about final product. And keeping the style with 3D is very easy compared to what I had to do with 2D. I already covered the costs of custom NSFW 2D art in this thread several pages ago, and these costs became only larger with time. There is the fourth option - training AI on existing art style, and etc., but this is a gray area, and it might not work out technically.
Best of luck to the developer with his sequel. The 3D models look like they were lifted from a really old Illusion sandbox game. I understand wanting to keep costs down by not having to commission 2D art but I can tell you right now it WILL drive away potential customers.
Thanks. I picked visual style of the base models for the ladies that I liked the most. People have different tastes, not everyone is into DAZ/MMD/other 3D model styles, I can't satisfy everyone and that is okay.
