This is a fantastically enjoyable game. Great writing, great characters, great gameplay with a heavy emphasis on resource management and completionism.
As porn, I find it quite unsatisfying. No images, and in general, even though I like the themes-harems, corruption, mind control elements, very sex-based world-it seldom does anything for me. A big part of that is that the protagonist is just someone I don't identify with. He's appealing as an RPG protagonist but not a porn protagonist.
That said this is legit one of my favorite RPGs ever. Here's some things that are great about it.
--Player Agency. LOTS of choices, they're meaningful, and they require actual trade-offs. There's not one clear optimal path for investments, relationships, research, or resource management. You think getting that money now will help, but it requires major trade-offs in the future. But if you hedge all your bets on the future, you miss some limited-time opportunities.
--Awesomely written characters. They all are believable as people and have consistent goals and motivations. Most of the minor characters even experience character growth, along with the protagonist.
--Great world-building. It really starts slow, and then you start getting more pieces, and then once you get a grasp on things...there's twists! Suddenly there's a lot more.
--Clever writing. At times trying too hard it ends up eye-rolling, but there's many times I've laughed out loud. There's a good bit of winking at the camera, and even though there's a lot of tongue-in-cheek with the worldbuilding, the characters are still realistic people.
In short: Not a fappable game at all, but it's a masterpiece of writing and gameplay.
