I think this one has about the same issues as some of the other popular AVN has.
From a porn game perspective, there is clearly not enough content (2-3 scenes per girl so far). Not a big problem - if the plot, character, setting, etc, are good enough, then the scenes are just a bonus right?
But if you look at this game from a non-porn game perspective, it gets a bit rough because porn-logic is used everywhere.
All girls are somehow top-model level of beauty. The 39 years old looks younger than most 25 years old in real life.
They are all single, somehow, despite being pretty open to relationship and generally fairly horny (some of them especially), apparently having waited so long for the MC to give them a good dicking. They all get talked into naughty things fairly easily.
Girls are walking stereotype for the most part. Alex and Nova are a bit interesting but others I have seen a thousand times already.
MC can casually be 7-timing the group of girls, some of them who are constantly talking to each other, but no one minds apparently. Some of them actually fantasize about the whole polyamorous and sharing thing.
Only girls are allowed to become proper allies, because...huh...I guess because wasting time on character that will not be fucked is a waste of time?
Men are either antagonists or comedic relief. Proper care is taken to make sure they are not seen as potential rival.
MC is chosen one, everything goes his way, be it in the main plot or in the girl's hearts. His cock makes porn stars ashamed of their size. When he goes fuck a prostitute, the prostitute says "No need to pay, it was just that good!". When he goes on a date with girls, he randomly find world-class treasures. He is generally rewarded for making poor decisions, which can be confusing if you play without a guide.
I could go on, there is a lot of stupid things to talk about I think, but I think I made my point. None of the above would be a big issue if I saw it as a porn game, but as I said in the beginning, it's hard for me to see it as one.
I guess I'm being pretty harsh in all fairness.
