Dreaming of Dana is the only game in this list that's good for a quick wank, giving you your first real sexual content on day one at work. Big Brother and most of its contemporaries, Man of the House, newer ones like Cure My Addiction, or even Summertime Saga, have sexual content in spades, but you have to grind for hours and hours before you get there. Moreover, with Big Brother in particular, it's a disappointing experience, as you get 10 renders of Max's Ass as you "fuck lisa in the ass" doggy style. Meanwhile, the first scene in Seraphim academy is a sex scene with 58 of it's 72 frames dedicated to the act itself, constituting multiple positions, different angles, and actually sexy shots. I admit, I haven't replayed MotH, but I don't remember being impressed with it's sex scenes either, though, that could be because while it could be used for a quick wank, if you wanted anything more out of it you had to grind those sex scenes like a chore, making them unenjoyable by default.
No, what made those games popular was the time in which they came out. They didn't have competition. No one was making quality content. I'm known for coming down pretty hard on Life Sims, but I'm all about Harem Hotel and Mythic Manor, and it's not because of Honey Select, it's because the devs put the time and energy into their projects to make them relatable and give a good amount of sexual experience with the only grind being optional content stuff that's still pretty fun to get, and great for that quick wank.
Art is subjective, but that doesn't mean that there aren't collective realities that make something subjectively bad for the majority. No one watches The Room and says "This is a masterpiece" they watch it and laugh at all the many many things about it that are subjectively bad to our collective understanding of quality. One of those things is believable characters. Big Brother fails heartily in this. Eric is a cartoonishly bad villain, dialed up to 11 with no cause whatsoever. Mom has 3 distinct and never mixing personalities, Eric's depraved whore, the mom who pays you for chores and does yoga with you, and the naive puritan who doesn't realize you're tricking her into satisfying your needs. Alice is a blank slate with her only traits being "I'm better than my brother," and "I don't trust that pervert." It's obvious she was supposed to be the bitchy older sister, like Veronica in Man of the House, or Tracy from Dreams of Desire, but that is never really used. Instead she's just the gold digging whore of the family. And then there's Lisa... Her story is literally about overcoming her aversion to and lack of experience in sex. Every time you take a step forward you have to take two back and convince her again. She doesn't once choose to move forward of her own volition, making you feel like the coercive rapist cornering her till she gives consent. The aunt is just max with a vagina.
The only character I did like, who seemed fleshed out, was Olivia, but, if you play the route where you get introduced to her later, she's a completely different character.
And because it came up, Big Brother is shit at NTR. Sorry to let people in on this, it is not NTR when your mom sleeps with her boyfriend. It's barely cuckoldry when you peek in on them and later are invited to watch, however, since she is not your partner it is not Netorase, because again, you have no claim to your mother. It's also not NTR when your aunt who you all but raped starts having sex with the same boyfriend, even if he blackmailed her with that initial sexual encounter to do it. However, there is one thing in that game that is NTR, the thing is, it's the least sexualized version of it. Max has a relationship with his mother that constitutes a bond of trust that is being broken but it's not a romantic one violated because she's having sex with Eric, but a maternal one because Eric is becoming abusive of max and his mother ignores or outright accuses him of lying and allows the abuse to continue. Thus, she breaks her maternal bond with Max, making him unable to see her as his mother anymore, and NTRing him. If there had been some sort of corruption plot where Max turned his mother away from Eric without getting the mob/sex dungeon involved, that could have been Netori, and thus NTR with Eric as the cuck, but that doesn't happen either, you just get rid of him.
People complaining about NTR in Big Brother, or campaigning for it to be liked because of it don't actually know what NTR is. Just because you're a character in a game who is supposed to be able to fuck the other women doesn't mean your character has a claim to them by default. In the case of Max, his claim has yet to be staked when Eric enters the game. If Eric had entered after there was a relationship, then it could theoretically be NTR. If Max had been fucking his family at the start of the game, it could be NTR. But as the game stands, you have some of the masochistic feelings of cuckoldry if you watch Eric fucking your family, but none of the relationship claim necessary to call it NTR, except on the grounds of the abusive relationship Eric causes.
