Absolutely. But it's overkill and reaches the point of not just Diminishing Returns but actually Negative Returns. This industry is drowning in low effort art, but it's also getting starved of good art. It isn't long-term sustainable that the games with the best art only release one or two updates a year.
It's negative returns from a business perspective, yes, because most people do not care about such high level of quality in the images, they do not even notice the difference.
For example, Stoper uses ZBrush to correct a widespread problem for DAZ users (clothes not fitting tightly to bodies). A problem which, when I sometimes point it out on other VNs (Being a DIK is plagued with that), hardly anyone sees it. They don't see while playing, they aren't able to notice when shown.
If you want to reach a large audience, you have to compromise on quality (or simply don't look for too many refinements), focusing instead on quantity and then frequency of updates.
The question, in the case of Stoper, is that he - I think - gives maximum importance to the artistic side, while the economic side, the turnover, interests him relatively. I sincerely have no problems with Stoper's vision, indeed I really appreciate his art, I find it worth the wait, but this is because I don't pay anything. If I paid every month, I'd ask myself a few questions, unless I was a very wealthy benefactor. I don't pay anything for this game (or others) but ironically, if Stoper did a course on how he works and how he uses the various software, I'd be really tempted to sign up, if the cost was affordable for me.
Thank you for informing everybody about that. That's great, we had been waiting for you to download this game for years. Everyone here has been asking for months: why CodeSlingerJames is not trying JOHN? Stoper has halted development because, I quote him "if CodeSlingerJames does not even try my game, my game is useless, I feel depressed". Therefore I think this is great news, Stoper will soon publish an update because he has found motivation to go on! You are our saviour!
