The game looks good so why the ratings are so low?
* The creator using the name of the original game purely for brand recognition, treating this one more like a playground for the writing team's OCs, with original concepts that made the first game what it is completely put to the side or outright ignored.
* Incompetent project management (Main plot not progressing for around 4 years, mismanagement of assets, etc.)
* Focus on futa content, because that's what the writers are into.
* Lots of abandoned content, which instead of being completed, is pushed to the bottom of the priority list due to the introduction of new characters that most of the time are incomplete themselves.
* One of the writers having it out for the players, writing spite content that is collective punishment for anyone who interacts with said bit of content, which is a requisite for one of the main companions' story progression.
* Writers forgetting about player agency and often writing scenes from their own character's PoV, instead of attempting to stay neutral. Just as an example that means that whenever your pc gets faceraped they're written to absolutely love it, or if your virgin pc gets their twat torn apart by hyper horsecock dickgirls, it's a mind-blowing orgasmic experience that your pc can't have enough of, regardless of your own feelings on the matter. Hopefully you enjoy getting cucked too, cause there's quite the bit of that whether you opt in or not.
* Endless amounts of plotholes in the setting. I personally don't give a shit but a lot of people are peeved about the inconsistencies or lazy, hand-wavey explanations.
* Questionable character writing, such as the primary companion and poster girl being a walking STD, the bro "bull" companion being written to be better than you at anything and everything so he can cuck you when the writer wants, and another being written as an abusive mother to a child where you, as the father, are locked into the role of a deadbeat with no chance of reconciliation regardless of your choices and actions. Said child also either grows up to hate you or becomes a whore, so you get that cute choice to make.
* Some minor peeves like typos that never get fixed, use of modern euphemisms such as "Jeez", making Jesus a secret member of the in-game deity pantheon, and wacky vernacular such as one of the writer's obsession with calling wombs "baby bags".
Oh yeah and my favorite one. The fact that this game "is not your power fantasy", so you get to play as a not-so-special not-so-chosen one who I guess can be considered to be the main character if you gaslight yourself enough. I think that about covers it?
