Okay so, impressions on the porn for now. Bear in mind I also don't know exactly how DAZ works, my closest experience is VAM and the morphs/models there, I don't know know how much control you have over the textures, expressions, and so on.
--As expected, uncanny DAZ things:
-Min's expressions were actually alright, but I had trouble distinguishing whether her smirk in the shower was meant to be shy or sexy - struck me like the former when it felt like the scene was going for the latter.
-The placeholder character model probably did not help, but even so, the blowjob expressions do not look right to me. I think they are lacking pucker.
-Live cam animations seem very stiff and anemic. Min's cowgirl animation was the only one I felt matched the pacing of the SFX.
-Audio SFX are nice as before, high quality and titillating, but unfortunate have a slight hentai edge to them. That worked fine for MotBB, but the constant mewling and exaggerated slurping does not fit the more realistic characters. I think this dissonance is least apparent in Min, and most apparent in Lore.
-Faustina is fucking terrifying. I feel like people always crank expressions on the Genesis models about 150-250% to where they should be. Too much expression, and the way their facial muscles tense and fold becomes, IMO, extremely unappealing.
-You have to do something about the whole taint/genital region. I know, that whole area and the glutes are by far the most difficult to make appealing and/or lifelike in these sorts of models, but that being said Min appears to have an unacceptable texture mismatch down under. The anus/slit blush likewise looks very strange, as if it was set to a higher opacity setting than it should have been. Faustina's hip/glute shape did not look right to me when she was eating lore out, but that's was a minor thing.
-Its probably not the majority opinion but I found the MotBB sex scenes more titillating. Not because I was blown away by the pixel art, but because the combination of visceral, kinetic movement with audio to match allowed my brain to fill in the rest of the details. I don't know, I just really value motion, and your new pornographic solution misses out on that, with the additional cost of losing out on some of the interactivity, and the flaws of the 3d models are more distracting to me than the extremely basic pixel art of the previous game, as the latter left much more room for the imagination.
-The cum looks horrendous.
-The prose is good tho, like in the last game, neither too purple nor too filthy, I enjoyed it. Although I think the MC dialogue options are largely unsatisfying - he feels too dense and/or unexpressive, neither dominant nor submissive, just bleh. "You're really good at sex."
-The breasts, likewise, are pretty cool, but that aspect of the model's anatomy is sort of like the opposite of the glute/taint region, its difficult to render breasts on these models in a particularly unattractive fashion.
IMO - and, again, I have no idea, maybe these type of sex-scenes actually makes most people throw their money and cum at the screen - if you are making a game using, shall we say, "derivative" models, it needs to be significantly better than what someone can set up 15 minutes after downloading VAM. The lighting needs to be on point (you seemed to have done a good job of that,) the sounds need to be good (almost nailed it, but not quite,) the models and expressions need to be as aesthetically inoffensive as possible and ideally the animations should be visceral. I think the most tolerable sexy thing I've seen that uses DAZ is Treasures of Nadia and all that jazz, though I had subjective issues with that game too - I'm just not a big fan of every character being a milfy bombshell, and the animations, while smooth, were far too anemic for my taste.
Overall, I'm sorry to say that visually, the porn looks too amateurish to me. Its something I did not climax to, not because I could not do so given sufficient application of fist-fucking, but rather, it just didn't feel enticing enough in the first place to bother. I would have had an equivalent or better experience reading a good erotica while listening to a recording from /r/gonewildaudio. But again, what's worth fucking one's fist to is a highly subjective (not to mention, deeply philosophical) matter.
On the other hand, the environments actually look great, and the character idles are decent, probably because they have more measured expressions and poses and, frankly, less is required of them.
