People here that hate on harem games because they think they're boring, I agree for a lot of harem games, which is why my rule is story first, sex second. But you shouldn't ignore the fact that the majority of NTR games have boring predictable plots too, just instead of the MC fucking every girl, the LI is turned into a BBC obsessed slut within minutes, despite her being portrayed as a faithful girl who loves the MC with all her heart at the beginning.
The point of me saying this is to tell you that you shouldn't be hypocrites, judge both equally.
