Personally I think the creator deserves a lot of credit for even attempting to go outside the standard "classic" NTR structure. I know it's purely a semi-mindless fap value kink for a lot of people, (as all kinks are), but even for those that aren't "turned on" by NTR, I think it does have a lot of value as a mechanism for adding additional depth, challenge & intrigue to a story. Whether that be as a gameplay challenge, to add complexity to the characters &/or the plot, etc... When used properly, it can really add a lot to craft a compelling story, while having plenty of things for everyone to enjoy.
The trick to doing it right is understanding the scale of content that needs to be created. i.e. if a "classic NTR" game has X volume of content, you don't stick to that same volume restriction & then split that volume between all content, resulting in less content of choice for everyone, but rather, expand the scope of that volume, so that it encompasses all that it could be. I think that's why a lot of the, (more rational), NTR kink fans look at games like this as lesser than classic NTR, due to the NTR content being drastically reduced in the final product to fit the same footprint. So for example, if his first game was a 2 GB "classic" NTR game, while the purely NTR kink fans may view it as a complete product, (which is valid, opinion is subjective after all), people like me see it as half of what it COULD have been, with the other 2 to 3 GB of what could have been a more expansive game left on the cutting room floor. That's what I'm getting at. When branching out to accommodate for more diverse outcomes, (meaning including "bad" classic NTR endings, happy, victorious for MC endings, bittersweet endings, revenge / pyrrhic victory endings), the creator needs to not be afraid to expand the story to that larger size. It's multiple variations of the story. Don't skimp on the content of any given variation, give all of them all that they would be as standalone titles & weave them together into a grander story. THIS is where not just NTR, but all story crafting elements truly shine. & this genre REALLY needs more of that.
To illustrate why I think that, Think of more conventional non adult games. Let's say... Borderlands as an example. Think of the Vault Hunter, (the MC), as the same as the MC in these NTR games, getting killed / failing quests as NTR & killing the enemy NPCs / leveling up / getting loot / advancing in the game as the alternate non "classic" NTR variations & branches in the game. Naturally, you want the full gammut. I mean if you use cheats to go into God mode & mow through the game effortlessly, (think of this like harem collector games, where the only point is to just go through the game boning all the female NPCs), that gets boring pretty fast. Likewise, just traveling around the map to let the MC just fail or get killed over & over, (the classic NTR analogue), again also get's boring, which stands to reason, as evidenced by the growing demand for NTR games with more variation that aren't just the same, "classic" formula again with a fresh coat of paint. I mean let's be real here. Sure, for those that just want some smut of choice to nut to, yeah, the same thing over & over & over again might be just fine for them, I mean why else would there be literally 10s of thousands of "incest" porn videos that are all literal clones of each other to the point where the "mom/sister stuck in the window/washing machine" trope is memed to death. But if they are just looking for quick nut material, what are they doing playing a VN, instead of looking up cheating porn, or on 8muses reading NTR comics that give them a LOT more fap content bang for their metaphorical buck? I mean if they are playing a VN, then clearly they want more than just something to nut to right? They want a story, they want gameplay, they want to explore where different choices may take them as evidenced by the strong preference for choice heavy VNs as opposed to the much more unpopular choice lacking kinetic novels. VNs by their very nature are substantially heavier on lore, dialogue & overall non fap value content, (said non fap value content being the VAST majority of the content), while in conventional porn, porn comics, etc... The hardcore sexual content takes center stage & makes up the vast majority of the content. Additionally, VNs also put choice & variation center stage by design. They are literal digital "choose your own adventure" games. So if they are choosing this, there clearly MUST be looking for more than something to nut to, (unless they are so mentally addled that they are somehow unaware that porn videos & comics that cater to their tastes exist, let alone are FAR more abundant & easily available online), they clearly want something more than the same, repeated cycle they've seen over & over & over again. Otherwise, what purpose does choice serve at all? The obvious purpose is to explore something different. With all that in mind, the preferred balance, going back to the Borderlands analogy, is more like what games like that actually are, where, if you do all of it. Play it with cheats, (the harem/god mode), lose over & over, (the NTR mode), or play it normally & get the full experience of the struggle of competition, survival, battle & progressing towards victory, (the balanced / more expansive mode).
I personally think that anyone that takes the initiative to even attempt this deserves a lot of credit.
