In advance, I'm really torn about this game. On one hand, it's extremely high quality, on other hand, I deeply hate some of the developer chocies here.
Let's start with the bad: the transition to UE5 is probably the most useless, timewasting thing the devs could possibly do. The game already looked great on UE4, it ran well, worked mostly bugfree, there's nothing meaningful the transition to the UE5 could provide to the players, but in exchange, it put the story development on hold for who knows how long.
On the top of it, the UE5 version is bad. Like real bad. For the literal first half hour of gametime it has zero interaction with any alive characters. It feels extremely empty, and it's empty by design. Devs said they wanted to give the game a proper intro, but in reality, a putting a Skyrim-like scene at the beginning would've given the game enough intro. The introductionary part of the UE5 version is terrible, and would absolutely stop me from playing any further.
Now, onto the UE4 version. I can honestly say I've never played such a complex, and well-made porn game as this. It's genuinely an RPG game that revolves around sex. The sex part is naturally integrated as a central part of the plot instead of making unlifelike saint-to-whore kind of story that we've all seen too much.
The game has several quests with varying quality. Some of them are genuinely so great that blow AAA games out of the water (the investigation quest for example) others are just basic fetch kind of ones. Or somewhere in the middle. A non-fetch quest, that wasn't thought out much. But even the fact that a porn game has genuine meaningful quests, and dungeons is a refreshing addition.
The game has a basic combat system too. Not too complicated, and honestly, it strarts out hard at first, but with very little progress it becomes too easy. I've seen worse in non-porn AAA games.
The most of the dialogues are pretty well written for their purpose too. Of course there are the random encounters that are repetitive, but in general, there's no room for complaint there.
My only real problem with the UE4 version is the sex part. The game has several sex scenes, but those scenes don't give the player much freedom. plus most of the time the fixed camera positions during the scenes are positioned behind some object, so the already bad camera angles are made even worse. By the lack of freedom in scenes I meant the game decides which scene it would play for which random encounter, and doesn't allow any change in that. And all of those scenes are basic penetration ones. They are animated well, but become repetitive after 6-8 random encounter.
All in all, great game, but I'm really afraid when it will get an actually meaningful update next.
