The problem is not the number of family/relatives characters in the game. The problem is how they are being portrayed and implemented into the game. This is partly because the writing in BB is not that great which results in inconsistencies of the characters. This then ends up with the sex scenes feeling forced and not the result of Max's hard work.
Just have a look at the 4 main characters:
1. Kira started with Max because she's a porn star and she doesn't really care.
2. Alice completely hated Max, but suddenly ok with sucking his dick because Kate told her to (not counting the drunk after clubbing where she isn't being herself), and then even ok having sex while being recorded!
3. Lisa started with "ewwww it's a dick, grosss" kind of character and suddenly yeah let's suck yo dick and threesome with Olivia because suddenly she's super horny girl
4. Ann gave pity handjob because carpal tunnel lol
None of those have any build up whatsoever. It's kind of like a switch and suddenly "OK". Then now suddenly Lisa wants romance, it's really backwards. The sex scenes are there, but the backstories are not. That's why things felt repetitive, because they lack context.
More content for Kate or Olivia doesn't mean that they would be the main focus of the game. Just because you're going to a steakhouse, it doesn't mean you are only going to eat steak. You can still eat side dishes that are not steak. You can still have drinks. You don't just go there and eat a piece of beef, and they don't only sell steak either.
Wow you missed everything about this game.
Yes you do actually win them over.
Alice is finally won over by helping her with her blog. You get her true feelings for Max if you get the candies before Kira shows up and do the Friday night Saturday morning scene.
This is only her outward persona and if you watch each pic you can pick up on her secret love for all her family. Typical big sister attitude is how she is portrayed. A lot of the passion is lost in translation but there are a lot of hints to this. The very first time you get to spank Alice when you catch her smoking and you chose the right response she thinks its a complement and if she hated Max this would not happen.
Now for Lisa it took me a long time to figure out, she is secretly in love with Max and if you play through the "You need to fight for him" path and if the english translation from russian would have brought the passion over you can see it.
There is still a lot of hints to this in the english game and if you look for them you will see them.
One of the first major tell tell is when aunt came in the first time for training, the next day she tells Max that Lisa got wet very fast and this is not normal for one who does not want it. The first major tell for this is when they both got off while Lisa was watching porn on her phone, she open up to Max at that time and showed her true feelings for him.
Go back to the opening story, what teenage girl who is offered her own bedroom turns it down to sleep in the same room her brother is in, this is the first hint from Lisa.
There are so many hints from the beginning of the story and through out the game.
"When there was a problem she would run to Max" "what teenage girl would turn down her own bedroom to sleep in the same room as her brother."
In v8 DS seems to be trying to change this but we will have to wait and see, I hope not.
Aunt Kari, she just wants to fuck and as long as it is mutual then she's all for it, but she still cares for Max in her own way. V8 I am not for sure what DS is trying to do now with aunt Kira so we will have to wait on v9 to see what happens.
As of 7.3 mom is a lost cause because of the rape and torture when she was a young girl and she secretly wants to be dominated because of it. Her story may get fleshed out in more updates but she is who she is as of now.
And just as any momma bear she will do anything and everything for her cubs/kids.
Ann in v8 has came a little out of her shell but very little has change so far.
There is so much more to this game if only you would look for it in the face pic's of all NPC's and learn to read what each one is trying to say to you.
