This is an unusually good game, and a very addicting one. Deserves to start being considered for the pantheon of "best adult games".
As an incest enjooyer I found Mario's storyline incredibly erotic. Disposing of his bitch wife to instead turn his daughter into his trophy wife. I wish there was more post-success content here, including the daughter getting more and more trophy-wife-like, getting a new haircut and dress instead of her usual self with her scraggly haircut, and seeing the wife actually move out of the house with more content instead of just hanging out idly by the pool.
I agree with others that Anna's love mechanic should not be explicitly tied to her Starmaker, since it makes some jarring leaps in the storyline if you're deliberately keeping your distance. I think the pacing in the journey from business associates to lovers could be a little more of a slow-burn.
I wish there was more end-game content, including expensive things to buy and money sinks, and perhaps a cap of starmaker growth. It gets really out of control where you're making millions per day and the most expensive thing in the game is like $50,000. It would be fun to delve into more evil paths toward the endgame, like a prostitution/pimping mechanic for Anna and others. This basically already exists in the story, but it's one-off with certain characters.
It's already a great game with tons of a content and it has sooo much potential for more.
