In terms of story telling, writing, characterization, and world building, this is one of the best games on this site. Deep Dimples has painted a nuanced and interesting society that he reveals bit by and bit, and I find myself completely engrossed in the story.
This is not, however, a porn game so much as a game that happens to have porn it in. Yes, the game starts off with a sex scene, a pretty good one at that, but unlike most porn games the point of playing the game isn't to just collect all of the sex scenes.
The sex scenes in the game serve more to reinforce the themes of the game and reveal character motivation. I would say that for the most part, they sex scenes aren't there for fapping.
There's a lot of hand wringing about "is the NTR avoidable" from the usual crowd, to the point where the dev has to start off the game letting people know that no, it's not. But that isn't really to suggest that this is a game that lovers of NTR would enjoy, because I don't really see sex as the point of the game.
The game is trying to tell a story. The main character starts off as an outcast, the lowest of the low, and he rages at his position. That most of the sex scenes in the game are NTR is mostly because it's there to illustrate the MC's inability to fight back against his environment, that he lacks the power to make changes.
It's implied that this changes, given that the very first scene starts off with a flash forward. What remains to be seen is how things will change. Given the world being described, it's unlikely that this would be a quick and easy lvl 1 to 100 power fantasy.
