In my opinion choosing to sacrifice Alice to save Kira is stupid. Kira, with her profession, a sex veteran, and her willingness to be sacrificed to protect the family, is the most logical choice. I understand the part of satisfying audience kinks though hence the choice.
Yeah it's stupid, but it still fits with how "brain-hurtingly" stupid most of the things that happen whilst Eric's in the game are, especially the characters.
Choosing to not sacrifice Alice and not get a blowjob from Kira when she's riding her sybian at night ties into the influence system regarding Eric's "control" over the women in the household. That's especially stupid since Kira's only doing it because she's being blackmailed by Eric, and to protect Max as much herself.
Logically Eric shouldn't have any sort of influence mechanic over Kira, but he still does and players have to counter it, because reasons.
That kind of thing (the stupidity of characters in general) is one reason why I don't understand some fans who say BB is a great game.
It's a "bad game" that was pretty much only held up by the quality of its renders of the women.
this game is complete or not?
It's incomplete and currently still abandoned.
