If I remember correctly, it took them about a year to release the game, so this seems to be their normal update rate, which I think is just another milking mentality.
In games made with Daz you already have everything ready, models, poses and etc..., you just put them together and render them in high resolution.
In the past, yes, these rendering processes took really long, but with today's technology this is no longer a problem.
And while you are rendering on the one hand, you can easily do your coding on the other hand.
When you start making the game, you already have a finished story.
Before some idiot asks me why I don't make my own game, I give my opinion on why it doesn't make sense to release updates at such long intervals.
By the way, I don't give a fuck what mentality they have, because I'm not paying for this game.
