The first and most obvious one is the quality of the CGs. Whenever someone posts a CG from Big Brother, people immediately go "Holy shit what game is this" - Because it just looks that much better than the average Daz fare.
So, here's the thing, for 25k a month his art could be 1000x better. He has no excuse for the fact that he doesn't have animated scenes. Kinney, the developer of Inevitable Relations makes art that is just as good if not better than Dark Silver and he's not making 25K a month. There's an artist on the Hub who makes some of the most well posed, well lit, high quality art I've ever seen with daz and he's not even getting paid. With the money the game is making there's no excuse for this. If DS isn't good enough to take it up a notch he makes more than enough to pay someone who is. Hell, he could pay several people who are and make his game much better.
The other thing that Big Brother does well, what is more subtle, is creating an "atmosphere of lewd" - Whatever you do, there's some lewd undertone to it. You move around the house, there's always someone to spy on, or someone to talk into a lewd massage. It creates this constant undertone of lewdness even when you're doing mundane shit like cleaning the pool, because there's the choice between that and letting your sister give you a handjob.
This might be the thing I hate most about this and similar titles. It makes me feel gross. Don't get me wrong. I don't really believe in true love or monogamy, so I don't care that the games are all about sleeping around. What I have a problem with is the chronic behavior of a sexual predator. The fact that the game is written from a perspective of someone who is taking advantage of his family members and not as someone who has legitimate feelings for them and them for him. In fact, while I would say that BB has better writing than MotH I would also say that MotH did a better job of making it feel like the characters were in this together than BB, which at every step makes me feel like the bad guy who is pressuring the women around me into a sexual relationship that they don't want.
This is why a lot of people criticize the NTR haters by talking about how Max is the least redeemable character in porn. He's the exact same person as Eric, the only difference is he doesn't have money and is related to the characters. Eric makes the perfect foil for Max because he is Max. Playing as max makes me feel dirty, and I eventually stopped because it wasn't getting better. I thought for sure after my little sister and I started the whole mutual masturbation thing that we'd start having an actual loving relationship, but it kept being one of convenience, where I was simply the only guy around and she was simply the next slut on my list.
A lot of games fail at creating this sort of atmosphere, because they're utterly linear and you have to go through 15 minutes of boring, non-lewd plot exposition shit -
Depending on the game this might be a legitimate complaint. However it might just be a stylistic complaint overall. For instance, my first release is gonna be about 45 minutes worth of game. It starts with a relatively violent sexual assault, then spends about a half hour just spending time getting to know the characters before it ends with two lewd scenes. So technically, you're going to have that 15 minutes of non-lewd plot. However I have avoided exposition as much as possible. The thing is, not all games are fuck fests. Not all games should be.
Now, if the game was the same style game as BB then hell yeah 15 minutes of some non-lewd bullshit would be a detriment, but again I'd prefer something non-lewd to something that makes me feel like a sexual predator.
Now what Big Brother obviously does badly is the grind. Whenever you need to repeat a scene identically X number of times when X is greater than 1 to generate progress - The game designer failed at his job
I think 3 would be a better number, but I'm glad we came to this part of the discussion because here is where I can really tear into BB. I won't cherry pick specific points from the rest of this because you and I totally agree with your post from here on out. View of Family is my go to to demolish BB and MotH. Mia from VoF is, in my opinion the hottest character in any of the porn games I've ever played. And the art on the whole is generally pretty good. The story with the characters progresses in a much less strange way, in my humble opinion. Now, that's not to say that there aren't repeated events, however, I think the dev has created repeated events that make some actual real world sense.
The situation with Mia specifically is really well done for me. First of all, she's already attracted to you. This, I cannot stress enough, should be the prerequisite for any and all incest games. Stop making me pressure women who don't want it into sex unless this is a rape game. Moving on though, you find out from her that she's not doing well in class. Being both her older brother and a tutor by trade, you offer to help her study, and then learn that she thinks the teacher might also just hate her. A few days later she calls you because she's in trouble at school and doesn't want mom to find out.
So you head over to her school and find out two things. First, her teacher is the teacher who you fucked in high school and got fired for having a relationship with a student. Second, the reason she was in trouble was that she was watching porn in class. So you, have her go wait outside and decide to have a talk with the teacher... and by talk I mean you get her to fuck you again, just like old times, and then blackmail her into giving your sister an A, because apparently the school doesn't know about her past. While you're fucking her though, you notice Mia watching you from the hallway and touching herself.
You later confront her about this and she explains that her boyfriend left her because she had no experience with sex, and eventually she begs you to teach her. You relent, deciding to do so, but on one condition, she has to sit with you and learn her subjects first. So you spend like two or three days tutoring her before you reward her with the first lesson. Then repeat that for 2 or 3 days again. Till the next lesson. However, this isn't the only way you interact with Mia. You also can go meet her at the beach for an hour every day, and you can find her in the living room for two hours each day. During those times you can get her to do certain evolving lewd things based on how far along you are in her sex lessons. Yes, these are repeated events, but the progression is swift enough, and their premise realistic enough, that they don't feel like grind.
The progression with the mom might even be better than the sister. Unlike the other, similar games, that have you advance progress with your mom through completion of certain events like in MotH where you try to massage her, then you get her drunk so you can go further, etc. That feels gross, because you're taking advantage of her. In VoF, once again... mom has feelings for you... even before you start to progress with her she tells you one morning that she had a dream that you and her had a family together, she laughs it off, but it shows early on that she's subconsciously seeing him as a potential mate. So when you go to watch TV with her and rub her legs casually it feels like a more natural courtship. However, this is an incest game, and incest isn't a normal courtship, so the stairway takes a bit more. I don't remember if the first Mother Son date happens before or after you talk to the psychiatrist about your mother's recent divorce, but regardless, you have a date with her, and in the heat of the moment kiss. Mom of course has an existential crisis because you're her son, but you are ok with it so you convince her to come with you to the psychiatrist again. This psychiatrist tells you its ok, that some people express their love in different ways and its good that you're getting closer.
Then of course, you go on another date, things go even further, and mom has another crisis. However this isn't normal. So before you convince the psych to talk to her again, you actually convince the psych into an incestuous relationship with her own daughter. This allows you to get her to convince your mother to go further with you and in turn things keep progressing in this fashion. Now, there is some grind in between all these events. But that grind is natural, its sitting with your mom, watching a movie, and rubbing her legs. Its going from rubbing her legs to her jacking you off, or letting you touch her. And yeah, it takes a few times to get her comfortable with more, but its not like you spend 25 minutes of gameplay repeating the actions more like 5.
But again at every point both characters are into this, both characters want the lewd activities to continue, to progress, to happen. It makes a huge difference in gameplay because it makes the female characters more than just archetypes with no will of their own. Instead of feeling like date rape, it feels like incest.
