I've been playing this game for years now. It was one of the first "harem" type games I ran across. I supported BD for quite some time. There's still a lot to recommend the game, but it's getting harder to do so for two main reasons, in my opinion. And no, it's not the lack of incest. This game was never likely to have any since the dev's family knows about his work. In my opinion, the two issues are: The rework not being done yet. This means that when you play the first half of the game it has little to do with the second half, because the second half references story elements from the first half that haven't been written yet. So there are sudden references to characters you don't really know, etc. Hopefully the rework will be done sometime next year and this issue can be put behind us, but it's really hard for new players to get into right now.
The second issue is the sheer number of LIs that you can add to your harem. This is a game, and there's suspension of disbelief and all of that, but there are so damn many LIs now that the MC is running out of time to see them all, and there's a push to get them all pregnant. I don't care how rich the MC becomes, there's no way he could reasonably support that many LIs and their kids. Plus, BD doesn't seem to be slowing down. He keeps adding more and more LIs. I think there's something like 30 LIs currently available or planned with who knows how many more coming. I'm not trying to yuck anyone's yum. I know lots of people like this game for this very reason, but I just don't see how BD can weave this many LIs into a satisfying ending.
I'll still play the game and I hope that BD manages to pull everything together, but right now I think it is more likely to come crashing down and leave most people unhappy. I do hope I'm wrong, though.
