I have a number of issues with this game.
1. Eric moves too quickly. I enjoy the idea of having an adversary, but I don't enjoy being a cuck. He should really move slower, so that you can get rid of him (before he gets any of your sisters) more easily without cheats.
2. Some of the quests don't line up. Here I'll be fucking Alice in her room on live cam, but when I massage her and she sees my boner, she tells me not to get ahead of myself. ???
3. Routes are still unfinished: notably, there's no good way to fuck Kira consistently, you can't walk in on Alice in the shower, and Olivia/her mom/Vicky are dead ends.
Overall though, the game doesn't really grind my gears. Many other people say that the grind sucks, and that it gets really repetitive. You're not wrong. However, it doesn't bother me, personally. I've played a lot of eastern MMOs; while yes, this gets boring, it's nothing like having to do the same 3 hours of daily quests over and over and over. For months.
This is a porn game, so character models are disproportionately important. And, especially when compared to almost all of the competition, the BB character models are hot af.
